Build an adobe house. How to choose an adobe house when buying. Interesting video: How to build a house from adobe with your own hands

When the name is mentioned adobe house many will ask what it is, or will shrug their shoulders skeptically, because they have a vague idea about it or associate it with a rural mud hut that has grown into the ground. However, today it is possible to build modern, beautiful and comfortable housing from the building materials that our ancestors have used for thousands of years. And most importantly - environmentally friendly, warm, energy efficient and inexpensive. It is these factors that become especially important when energy prices creep up and synthetic materials are everywhere. Therefore, it is worth taking a closer look at the technology of building a house from adobe and considering its positive aspects.

And first, let's figure out what this construction material what properties and characteristics it has, how durable it is.

Saman: what is this?

Adobe consists of components that are available to every developer and cost almost a penny. Its base is clay, the filler is chopped straw, fibrous plants, and manure. To give the clay the necessary viscosity, water is added to the mixture. Clay is chosen with medium fat content (low-fat clay gives poor adhesion and does not provide strength) and, if desired, various additives are added:

sand, crushed stone or crushed expanded clay can reduce the shrinkage of the structure;
adhesive compositions: casein or liquid glass provide the building material with good ductility;
cement and lime increase the resistance of adobe to moisture and promote its hardening;
cellulose fibers increase the elongation coefficient of the material;
shavings and sawdust increase heat-shielding properties.

Since adobe is valued for its environmental friendliness, it is extremely rarely used in its composition. chemical components, but sometimes, wanting to speed up the hardening process, developers resort to appropriate additives.

Two types of adobe are used in construction:

Lightweight, containing just over 10% clay. Bricks or blocks are not formed from such a mixture, but are used in frame technology, filling the outer and interior lining walls
Heavy. Blocks are made from it. Having thoroughly mixed the ingredients, the mixture is laid out in molds and left to dry outdoors. The density indicator of a raw adobe block is almost no different from that of brick and is characterized by a value in the range of 1500 - 1900 kg per cubic meter. But the thermal conductivity of adobe is almost twice as low. Moreover, this indicator depends on the straw content in it: the more straw is added as a filler, the warmer the future house will be.

Any building material cannot be considered ideal, since it has, along with positive qualities and disadvantages. Saman is no exception, therefore, when talking about him, it is logical to dwell on this point, finding out all his advantages and weaknesses.

Adobe house: pros and cons

So, what is good about a house built from adobe with your own hands? To its obvious and undeniable advantages both builders and residents include:

Microclimate favorable for human health. Due to its high hygroscopicity, the material is an excellent regulator of indoor humidity.
Low thermal conductivity. The house perfectly retains precious heat in the cold and coolness in the hot summer season.
High sound insulation ability.
Low cost compared to other building materials.
Environmental friendliness and fire safety.

Adobe is comparable in plasticity to concrete, so it is easy to give building structures interesting shapes: curved walls, rounded corners and openings, unusual arches. And unlike walls made of monolithic concrete, which are cold to the touch, adobe is warm.

And one last thing. If anyone doubts the strength of houses for which adobe is used, then it does not hurt to get acquainted with significant facts that testify to the longevity and solidity of such buildings. On the territory of our planet, thousands of houses made of adobe have been built, the age of which is estimated to be centuries, and our contemporaries still live comfortably in them.

As for the disadvantages of adobe buildings, there are few of them:

The need to protect adobe walls from moisture, since the material does not have good moisture resistance. For this purpose, the surface of the walls is carefully plastered.
In areas with a temperate climate, built adobe houses take a long time to dry and gain strength.
Limited time frame construction, because winter period They don’t build adobe houses.

Another serious drawback is the possibility of the appearance of fungus and other harmful microorganisms. Such unpleasant moments can be prevented with modern antiseptic and disinfectant additives or wall treatment special compounds. It is not recommended to build adobe houses in damp and shaded areas, as the walls will be damp.

Do-it-yourself eco-adobe house

Construction adobe house It will appeal to people who are far from being experts in the construction business, but who have the time and desire to build and experiment. The technology is quite simple and does not require special skills.

Any construction is divided into stages, and in the case of an adobe house, the process will consist of the following types of work:

A ready-made and dry adobe brick will not break if dropped from a height of 2 meters, and will not get wet if it is in water for 24 hours. It is recommended to carry out such a quality assessment before putting the material into use.

Floors in an adobe house built with your own hands are wooden beams, supported on wall structures by at least 15 cm, are used as lintels for window and door openings wooden boards, wrapped in waterproofing material.

An adobe building requires mandatory finishing of the walls, otherwise they will crumble. Usually the base surface is plastered or covered with various finishing materials. Cannot be used only cement plasters, since the material has poor adhesion to clay.

As you have seen, building a house from adobe with your own hands is a feasible task for many developers and in terms of minor financial costs, and in terms of ease of construction. But technology does not allow building housing very quickly and carrying out work at any time of the year.

Adobe houses were almost completely replaced by brick ones around the 70s of the last century. With the advent of foam blocks, adobe was completely forgotten, but not for long. Now a gradual revival of the adobe house is beginning, because it is truly of natural origin - this is now most valued.

Like any other material, adobe has its pros and cons. In this article we will try to characterize as objectively as possible positive aspects adobe construction, but let’s not forget about the shortcomings.

A little history

The word “saman” itself came to us from Turkic, where it is translated as “straw”. IN different regions they approached the production of adobe differently: some peoples used clay, some used ordinary black soil; in some places they added straw to the solution, and in some places they abandoned it. Difficult to write exact recipe, which was used to make adobe in the old days. But we will retell from memory the words of one person who lived in the south of Ukraine. These places, as you know, were famous for their adobe houses, which still remain residential despite their venerable age.

A traditional Ukrainian hut made of adobe and a thatched roof is the best dwelling, proven over centuries.

To produce adobe, it was necessary to attract more people. However, there were no problems with this before: if a person asked for help in construction, then almost the entire village responded and construction took place in a matter of days. Then it was a normal phenomenon, let us note, not at all like it is now, when your own brother can turn his back on you.

A small pit was dug in the ground. The soil from it was also used for production. If there was a horse on the farm, then the pit had round shape– the horse walked in a circle, mixing the solution better and better than several barefoot people.

The finished solution is still just a shapeless mass.

Straw and clay were poured into this pit, sometimes adding horse manure, which acted as an adhesive mixture. By adding water and constantly stirring, we ensured that the whole mass resembled plasticine. Next, the mixture from the pit was tamped into the simplest rectangular shapes (four knocked down boards) and left on level ground in the sun. Within a few days, the adobe was completely dry and ready for use at the construction site.

The adobe blocks varied in size - there was never a specific standard. For example, we know of adobe with dimensions of 500 mm (length), 170 mm (width) and 120 mm (height). Maybe, smaller size I didn’t want to do anything to make the construction go faster. And there is no point in making more blocks either - they will take a long time to dry, and then the heavy weight will have to be dragged manually.

Benefits of adobe

The advantages of adobe blocks are still remembered by older people who either had to participate in construction or live in an adobe house.

Disadvantages of adobe

Cob houses also have disadvantages, but these disadvantages can hardly be called critical.

Since the weight of the walls and their pressure on the ground is very noticeable, it is necessary to give Special attention foundation. However, one can argue with this. We came across a building made of adobe blocks, where the foundation was presented lime mortar in a pit with dimensions of only 300 mm (depth) and 600 mm (width). The base was made of flat stones to make it easier to start building the first row.
Rodents or insects may live inside earthen walls. Unfortunately, this is true. It will not be difficult for a mouse to gnaw through an adobe block in the place it needs in order to organize a nest there. However, the mouse will not want to get inside the house if certain odors of treats are not reaching it. It is unlikely that you will store grain in your house, so rodents will find your house boring.
When attaching shelves or wall cabinets are faced with a problem. If you can install a dowel in a brick and it will certainly support the weight, then in the case of adobe, difficulties arise. For example, we had to use 200 mm nails, and before that we had to grind down the head of each nail so that it would go through the cabinet mount.
Mandatory plastering on the outside is a necessity so that rain and snow do not cause the adobe to “float.” Note that blocks are stored appearance even several years without finishing. The density of the material affects it and adobe can only lose a little in size and become completely damp unless there is a complete absence of wind and sun.

Instead of a conclusion

Adobe houses, the pros and cons of which we have analyzed, can be put on a par with wooden buildings and even higher. Indeed, in the case of timber, various chemistry can be used in the form of impregnations, paints and varnishes or primers. But with adobe you don’t need all this. Write comments, ask and we will always answer you. Moreover, our experience is practical, not bookish - this is very important.

Throughout the history of construction, mankind has used different natural materials. For a long time the most popular was ordinary clay, which became widely used in creating various types buildings Adobe, or adobe, buildings are becoming popular today not only because of the love of antiquity, but also for practical reasons - a house made of adobe in a difficult economic and environmental situation shows its relevance in the best possible way.

Material without time

Adobe, which is the predecessor, is a composite type material; it consists of water, straw, sand, clay and earth.

Raw brick made from clay with the addition of crushed straw has been used for thousands of years. Built from it and ordinary houses, and majestic structures, which confirms the use of adobe in the construction of pyramids in Peru and Egypt, and the creation of the Great Wall of China. and houses made from this material are found in Moldova, Turkey, Iran and other countries with hot climatic conditions, as well as in Kuban and Stavropol.

Not long ago, adobe building material became popular again: architects are embodying the ideas of experimental buildings with the concept of the unity of civilization and nature, and ordinary citizens are successfully building eco-houses on their own. Their results differ mainly only in design, since the technology has not changed for several millennia.

Building with blocks

The production of adobe today is carried out, as many years ago, using clay, sand, water and organic fillers (flax fire, straw cutting). In this case, the average amount of clay in the mixture ranges from 4 to 20% (with a decrease in clay, shrinkage of the walls decreases). In the block construction method, sand, clay and straw are mixed to a uniform consistency, then the blocks are formed into a wooden mold. Its inner surface should be planed and have some “margin” to simplify the removal of bricks.

Since the products are not fired, but dried in the sun (for 7-11 days, depending on weather conditions), their molding begins in the spring so that the required amount of material has time to dry over the summer. Ready bricks do not lose strength when driving nails, are easy to chop and trim well

Casting material connection

The casting method of construction is characterized by the manual laying of lightly set adobe masses onto the foundation using shovels or forks. The new layer is left to dry for several days, then the next one is formed. As the walls dry, they are cleaned and leveled on the sides. Characteristic feature is that all the layers that are superimposed on each other, in addition to gluing, are also held together by weaving straw fibers. For this purpose, the plane of each layer is deliberately left uneven, with protruding fibers and holes.

Construction Features

It is possible to use steel panels and formwork during construction. In this case, adobe brick is fed into a formwork box, standing in the design position, slightly moistened with water and compacted in small layers using wooden tampers. The clay remains in the formwork for about 3-4 days in cloudy weather or 2 days in sunny weather. Afterwards it moves higher and the next part of the walls is made. In each method, during construction, window and door openings are formed, along the top of which a steel or wooden lintel is mounted.

A house made of adobe can have any wall height. There are historical examples of buildings with several floors that are not only in excellent condition, but are still in use. Such structures, unlike earthen versions, the walls of which are held together by gravity, are based on a three-dimensional structure of interwoven straw fibers, the overall strength is provided by a large number of individual stems. Moreover, most adobe houses have no more than one to three floors. Such a house, like any other building, requires a reliable foundation and a strong roof to protect it from the destructive effects of water. The walls have a traditional rainproof coating in the form of cement mortar or lime plaster.

Advantages

Construction from adobe is the safest of all methods using natural materials. It is made from renewable resources and is non-toxic to humans, which is especially important in the current situation of severe environmental pollution and resource depletion.

Thanks to plastic abilities, it is possible to create architectural organic forms with the formation of niches, arches, curved walls - this is how a builder works with a house as with a sculpture.

It has a minimal cost compared to other materials. To erect buildings there is no need to use expensive specialized equipment and work force, respectively, high consumption There are no energy resources.

Water resistance and thermal insulation characteristics

The material is able to withstand long periods of rain and is not subject to weathering. For example, in the UK, which is characterized by high rainfall, there is great amount adobe comfortable houses, many of them are more than 500 years old. And in the nine-story medieval houses built with partial use of adobe, which can be found in Yemen, people have been living for almost 900 years. The special design and composition of the material can provide sufficient seismic resistance.

Saman is distinguished by large thermal insulation properties compared to brick, stone or concrete, therefore such houses do not require increased heating in winter and cooling in summer. This is a fire-resistant building material that is used to form chimneys and stoves, which is why it is optimally suited for homes in regions with a high fire hazard.

Adobe buildings are undoubtedly unique, as is the fact that they performance characteristics and economic qualities deserve the attention of every person who cares about the ecological future of the Earth.

Flaws

For adobe, the most difficult test is freezing - the main cause of destruction and cracking of houses made of earth. But use in cold regions is possible subject to special technology and external wall insulation.

Adobe brick doesn't have the best decorative characteristics, while being characterized by low water resistance. Without proper treatment in a damp climate, such buildings absorb moisture and begin to deform and crumble. To prevent such changes, walls with outside they are finished with baked ordinary bricks, and protected from the inside with a vapor barrier. In this case, a house made of homemade blocks will last much longer.

Important aspects

Blocks for building a house are placed on a solution of sand and clay in the proportions compiled for the manufacture of the blocks themselves, without the use of straw. For the first row, separation from the foundation using waterproofing is required. Reinforcement mesh will strengthen the joints of the walls and corners. Point loads are destructive to the material, so floors and beams are formed with an equal distribution of loads on the walls. Such a house, if it complies with all the rules, will delight its owners for many years.

Compound

Adobe brick, as noted above, consists of the following components: water, straw, sand and clay. In construction, the proportions of all components by trial method and mainly depend on quality characteristics clay. She doesn't appear in pure form in nature and always contains some amount of impurities, most often sand. The total weight of adding sifted river sand is determined by the degree of fat content of the clay.

It can be found in places where it is mined by builders and stove makers. It is possible to use soil excavated from a foundation pit if the site has a clayey soil type. The clay from which blocks will be prepared for building a house must be free of stones, debris and foreign impurities. When harvesting large quantity material, it can be placed under a film and left to age - its quality will only increase due to this.

Used in making optimal size grain is at least 1 mm. Adobe blocks cannot be formed from dust variants. Roots, debris and foreign matter are removed from the sand, then it is sifted and dried.

Any type of straw is suitable: barley, rye or wheat, the main thing is that it is completely dried and has no signs of spoilage. Fresh straw works best.

Water is the last integral part mixtures, but not in importance. The strength of a brick is influenced by its purity, since water containing acidic salts contributes to rapid destruction. The best option is water from a well or well, without the presence of chemicals.

How to make adobe: determining proportions

To find out the proportions of the components, you need to take one part of sand and clay, add water, mix thoroughly and knead a solution that is similar in consistency to stiff dough. Then an equal ball is rolled out of the solution and left in the sun for an hour. Then it needs to be dropped from a height of about one and a half meters onto a flat plane. The ideal ratio of sand and clay will maintain the appearance of the ball. If it crumbles, then a reduction in the amount of sand is required; if the ball becomes flat without cracks forming, it is necessary to increase its portion accordingly.

Molding

Adobe brick is formed in plastic, metal and wooden forms in the form of a box without a bottom with several cells of a certain type. IN self-production The simplest forms are made of wood, made from planed boards with a thickness of about 30 mm.

After determining the required size of the blocks, a drawing for the form is drawn up, and the boards are subsequently cut from it. They must be connected at all joints in several places with self-tapping screws. The number of bricks produced at the same time can be any, it all depends on its size, but it is worth considering that the form should not have too much weight. Can be equipped with handles on the edges for ease of movement.

Unfortunately, funds are limited and, of course, there is a mortgage. In our city, the only houses available to me are adobe lined with brick, so I want advice on how to choose, what to look for, where to look, what to touch? Recently I looked at an adobe house lined with brick. And mostly silicate brick. (White) Inside the walls seem to be smooth, but the ceiling throughout the house is covered with a network of cracks, in some places even large ones, and at the junction of the walls and the ceiling there is also a crack about 1 cm wide along the entire perimeter. I'm waiting for your advice. Thank you in advance.

Alexey, Novocherkassk.

Hello, Alexey from Novocherkassk!

Adobe houses. There has been a lot of talk about them lately, both good and bad. They remember their entire history of construction from many thousands of years ago to the present.

Adobe (from Turkic - straw) is a material made from a mixture of many components, ranging from clay and sand to various organic additives. But nowadays they can cram so many components into it that “Mama, don’t worry!” Previously it was simpler, add dung (manure), which by the way is an excellent binder, and that’s the end of it.

However, read about this in special literature or pages on the Internet, there is a lot of information about adobe houses there.

Let's just briefly go over the most noticeable pros and cons of adobe houses.

Pros.

Adobe is one of the cheapest materials in housing construction. Clay, sand, straw or its analogues from organic fillers and water. All this is accessible and literally lying under your feet. Take it, make blocks, build. Add to design wooden elements, roofing, glass for windows and the house is ready. A light rubble foundation and a brick stove will complement the structure of the house.

The house usually has a constant microclimate with normal humidity premises. When the humidity is high, the walls of the adobe house take it away, and when the humidity is low, the walls return the moisture back. That is, the environment is good. Due to thick walls, and they are not made less than 40 centimeters thick, and more often they are even thicker, passable thermal insulation is maintained and so-called thermal inertia exists. High sound insulation. Depending on the amount of organic additives and special additives, an adobe house can have high fire safety.

Moreover, since clay contains chemical element aluminum, then this metal is capable of shielding, that is, reflecting electromagnetic waves from external sources electricity. This effect of protecting the human body has not yet been studied much, but it does exist.

Minuses.

Adobe does not have high moisture resistance. And to improve it, it is necessary to use plasters or, at a minimum, whitewash. In your case you are talking about the lining sand-lime brick. Also not superfluous. Although fired clay brick would be better, silicate brick also does not like moisture.

If, when preparing adobe, the builders overdid it and added a lot of organic additives (straw, chaff, bonfires, chaff, reeds, etc.), then there is a high probability that not only bugs, spiders, and other insects will live in this organic material , but also rodents in the form of mice and rats. And organic matter in large quantities can ignite more often than in small quantities.

We cannot discount the possible presence of radiation doses in adobe that are higher than permissible. Therefore, it would not be superfluous to check the background of the walls with a dosimeter.

When buying an adobe house, pay attention to external condition walls, ceilings, the presence of cracks in window and door openings, mating planes in corners and along the ceiling. If they are beyond the limits, then this indicates large sediments of the adobe mass. To seal gaps and cracks in the future, use either simply redecorating(filling them with plaster), or up to installing metal or plastic plaster mesh on the anchors and applying a two to three centimeter layer of plaster.

Checking the condition of the wood structural elements Houses. These are frame beams or beams along the bottom and top of the building, ceiling beams, above window and doorways, framing of the windows and doors themselves. Rottenness is not allowed, otherwise they will have to be replaced at certain costs. /By the way, clients who bought an adobe house often install new plastic windows instead of old ones./

It is worth paying attention to the smell inside the premises. If there is the presence of mustiness, then this indicates possible rotting of organic additives in the wall mass. And also check the walls for moisture and the presence of mold and mildew. And the depth of settlement of the foundation and its base. In old houses it is sometimes unacceptably large; the floors sometimes lie directly on the ground and it is very difficult to lift them. And even after redoing all the floors along with their joists, you can get them so raised that it will be within easy reach of the ceiling.

Yes, and the presence of ventilation under the floor is mandatory. Why should there be ventilation holes in the base of the foundation (that is, its above-ground part) - a couple of them for each wall of the house with a diameter of about 15 centimeters.

In addition, with heavy adobes (with a low content of organic additives), you will need to take measures for additional insulation of the walls and ceiling.

Some clients are thinking about adding second floors or attics over an existing old adobe house to increase usable living space. This should be treated with great caution; not all walls are able to withstand such additional load.

Here sample list points that you should pay attention to when buying an adobe house.

It is not superfluous to talk with the owners of old adobe houses about the shortcomings that are present in the houses. (Not with those from whom you are going to buy a house, they will never tell the whole truth, because there are two fools at the market - one sells and the other buys. Just a joke.)

And the last point, not entirely related to the topic of adobe houses. Think a hundred times before getting into a mortgage, it’s such a bondage! However, this is your competence.

Other questions on the topic of adobe houses.

Adobe houses are becoming more and more in demand, because they are not only environmentally friendly housing, but also energy-saving, and therefore very warm. Today, to build such a house is large financial investments will not be required due to the low cost of the necessary building materials. And if you wish, you can prepare adobe with your own hands and build a house yourself.

Feature of the material

Adobe is made from a mixture of clay, straw and sand. IN construction industry it is called raw brick. Ceramic brick differs from adobe in that adobe is dried in air, while ceramic is dried in ovens.

One-story buildings are erected from adobe bricks, and, less commonly, fences, but only in dry climates, since frequent rains destroy the material over time. It is worth noting that adobe has been used in construction for thousands of years. Even the Great Chinese Wall contains adobe material.

Light adobe is most often used in construction. It is dense and durable, does not burn and does not sag. In addition, it retains its shape well and, most importantly, “breathes.” Lightweight adobe is cheap, ideal for filling frame construction, playing the role of insulation. Its components are clay and straw, and therefore such adobe is environmentally friendly and absolutely non-toxic.

Flaw light adobe– these are possible impurities of dirt at the stage of its preparation.

You can see in more detail what a house made of light adobe looks like in the photo.

The difference between heavy adobe and light adobe is that for the construction of a load-bearing light wall adobe is not used because it is too thin; it is most often used for filling wooden frame the buildings. Heavy adobe contains more clay, so it is suitable for the construction of load-bearing structures.

Features of adobe houses

Among the features of adobe houses are:

Reliability and durability. Having prepared good foundation and a reliable, leak-proof roof for an adobe house, the structure can last more than five hundred years, thereby outliving traditional frame houses. The strength of an adobe house is ensured by the tightly interwoven straw fibers in the structure of the material.
Lack of dampness and ability to retain heat. The adobe wall has an approximate thickness of more than 30 centimeters, while having the ability to accumulate and retain heat. In summer, adobe houses are comfortable cool, and in winter they retain heat.
Affordable price of adobe. This is a very cheap building material.
A house made of adobe is built very quickly. In addition, after the construction of the adobe frame, it only needs to be plastered without other additional work.

The benefits of adobe are :

Resilience to climate change. The ability of adobe walls to reduce heat when outside the window heat air. It will take about a day to transfer heat or cold to a 60-centimeter wall. In winter when stove heating adobe house, its walls warm up well and remain warm for about another 10 hours.
Plasticity and strength of the material. Houses made from adobe material are highly durable. If you maintain an adobe house in proper condition, it can last for about a thousand years.
Noise absorption. Due to its structure, adobe does not conduct sounds well. Therefore, some people build adobe houses near the roads, railway tracks and factories. Adobe walls absorb not only noise from outside, but also sounds from inside the house.
Adobe as a building material is safe for health and does not contain toxic substances.
It has fire-resistant properties and is widely used for making chimneys.

The disadvantages of adobe are:

Weak moisture resistance. Adobe walls on the outside require plastering and protection from precipitation.
Mice can live in the walls, since it will not be difficult for them to gnaw through such a wall.
It is advisable to erect the structure in summer and spring, since in winter this material is weakly pliable, the use of alkalis is necessary.
Adobe blocks take a long time to dry.

Adobe is unsuitable in the following conditions:

structures are not erected on steep slopes;
in the shade of trees;
in areas where flooding occurs frequently.

Choosing material for adobe house

To build adobe you will need:

Clay. Clay for building an adobe house is often mined outside the city, in a mine site, in a quarry, or in dug trenches at the site of future construction. The clay must be oily or medium, in which case it will not crumble. Externally, the clay has a red, ocher color, grey colour. But dim gray. In some places you can find clay deposits that are green, white, black, and so on. You need to understand it well so as not to make mistakes. You can also find clay near various bodies of water, for example, at the bottom of a lake. Its properties are waterproof. To check if you really have found clay deposits, take a small lump and mix it with water. If it becomes very plasticine-like and sticky, then it really is clay, suitable for forming adobe bricks.

Straw. Dried winter wheat is suitable as straw. Rye and barley straw can also be used. Required condition– dry straw or coarse grass hay.

Sand. For adobe blocks, sand made from large particles (approximately 1.9-2.1 microns) is used. The structure of the sand should be multifaceted, but not round. Good fit quarry sand. Sea and river can be used as a last resort.

When planning construction from adobe, it is necessary to prepare the clay in the fall:

Clay is laid out in layers in a special pit (burt) dug on the street. Dimensions of the pit: H – 100 cm, D – 200 cm, W – 150 cm.
Layers of laid clay, about three meters high, are filled with water. The top is covered with wet straw. The straw is covered with roofing felt or other covering. This amount of clay in the pit will yield approximately 600 adobe blocks, measuring 2x2x4 m.
At the beginning of March, the covering is removed along with the straw layer and covered again with a polyethylene film, creating a greenhouse for the clay. This way it won't dry out and will retain its stickiness.

Making adobe blocks

To make adobe blocks you need:

First of all, thoroughly mix the clay and sand, adding water and straw. The consistency is thick.
A ball of similar size is rolled out of the clay-sand mixture. egg. The correct consistency is determined as follows: if the ball sticks too much to your hands, then sand is added, if the ball crumbles, clay is added.

To determine whether the consistency of the composition is correct, you need to dry the ball of adobe composition and drop it on the ground. If it doesn’t crack, it means everything was done correctly.

Technology for forming adobe blocks:

The construction of a house from adobe begins with the formation of blocks of the required sizes. To do this, use bottomless boxes made of wooden planks, about 25 mm thick.
The finished forms are pre-moistened with water and sprinkled with small grain waste, such as chaff. Then compacted ready mixture into blocks.
The blocks are dried in a draft. After three days, they are turned over and dried for another week. Then two blocks are placed on an edge.
The readiness of a brick is determined by its color. Throughout the block its color should be the same. It must be solid. To test an adobe block for strength, you need to put it in water. If it does not dissolve or soften within 24 hours, it means that the result is a high-quality building material.

Construction of an adobe house

If you wish, it is quite possible to build a house from adobe with your own hands. It is only important to provide yourself with all the tools, such as:

digging tools - shovel, hoe, pitchfork;
large containers for water and mixing plaster and storing materials;
level for leveling the surface;
a large, strong knife for cutting adobe;
a pocket knife for cutting tarpaulins and other materials;
wooden sticks for creating holes in adobe blocks;
tools for transporting materials, a construction wheelbarrow is most suitable;
large volume barrels for water;
sprayers for spraying adobe;
sieve with hole sizes 1.25, 0.6, 0.3 mm for plaster;
wooden shovel for mixing plaster and floor mixture;
axe, saw;
watering can or hose with running water;
stairs, scaffolding, rags for wiping off dirt, buckets, gloves, tape measure;
a trowel for plaster may be useful;
crowbar, safety glasses, glass cutter, marker for marks, rope.

To build a house from adobe, you need to plan in advance the height of the ceiling, which in an adobe house must be made 30 centimeters higher, because adobe construction sags over the years.

To prevent rodents from getting into the house, bottom part The walls need to be reinforced with a metal mesh, and all wooden elements should be treated with antiseptics and waterproofed.
