The formation of market relations in the economy of Kazakhstan predetermined the creation of a new concept for the production of basic types of building materials. Based on the current problems of the construction complex, the creation of new and improvement of existing technological processes should be aimed at the development and production of efficient and competitive building materials using local and non-traditional raw materials that have high operational properties. To implement these tasks, it is necessary to use innovative technologies in the production of concrete. This material has been used for many centuries, is being improved and developed. Currently, specialists from diferent countries are developing high–strength concrete of a particularly dense structure-fine-grained concrete with high strength indicators. Fine-grained concrete belongs to the category of heavy concrete, its advantages are a high coefficient of strength in the process of bending and stretching, frost resistance and water resistance. Due to these properties, the mixture is often used in the repair of seams, cracks, in the sealing of various deformations, as well as for the creation of reinforced structures and products in the production of thin-walled structures with thick or complex reinforcement. The use of chemical additives in concrete technology began in the 1940s and is widely used in many countries. Currently, chemicalization has become one of the directions in the development of concrete technology.
