The effect of polysilicate on the formation of cement stone
Problem statement. Siliceous materials have long attracted the attention of technologists -in concrete. Currently, many organosilicon products appear on the market for related fields, the effect of which is not appreciated. Results. In this work, we study the effect of a new polysilin brand - Silin VN-M manufactured by HIMUNIVERS LLC (Kazan) on the properties of cement paste and stone. The obtained contractual dependence of the strength of cement stone on the amount of the ultrafine additive Silinoma VN-M has several peaks that lie in a very narrow concentration range. The first peak (extremum) lies in the region of thousandth values (1,97-10<sup>-3</sup> % of the mass of cement), and the subsequent peaks corresponding to the hundredth and tenth values are significantly lower than the first. Conclusions. A positive effect of introducing silinom into cement systems, depending on its content, was established in the work, and the maximum effect is manifested at a dosage of less than 0,001 % by weight of cement. Research materials may be useful in modifying cement systems.
