* The requirement for the content of alkali oxides in cement is applied by agreement between the supplier and the consumer
5.1.3 It is allowed to introduce additives into all types of cements - auxiliary components that meet the requirements of GOST 31108. At the same time, in cements of types TsEM P and TsEM Sh, the total content of additives - main and auxiliary components should not be more than indicated in Table 1 of GOST 31108.
5 14 By agreement between the supplier and the consumer, it is allowed to add plasticizing additives to the cement during grinding in an amount of no more than 0.5% of the cement mass in terms of the dry substance of the additive. Plasticizing additives should not be used if they do not combine well with super- or hyper-plasticizers introduced into the concrete or mortar mixture during their manufacture to reduce water demand and/or increase the survivability of these mixtures.
5.1.5 To protect against moisture and air and extend the shelf life of cement, it is allowed to add hydrophobic additives to the cement during grinding in an amount of no more than 0.3% of the cement mass
GOST 22266-2013
in terms of dry matter of the additive. Hydrophobized cement should not absorb water within 5 minutes from the moment a drop of water is applied to the surface of the cement.
5.1.6 In the production of cement, to intensify the grinding process, it is allowed to introduce technological additives that do not impair the quality of cement in an amount of no more than 0.5, organic additives - no more than 0.1% of the mass of cement in terms of the dry substance of the additive. In this case, the total content of all types of organic additives introduced into cement should not be more than 0.5%
The effectiveness of technological additives when first used, as well as the absence of their negative impact on the properties of cement and concrete, must be confirmed by test results in accredited testing centers.
5.1.7 The compressive strength of cement of the corresponding class and strength subclass is given in Table 4.
