THE EFFECTIVENESS OF USING A POLYFUNCTIONAL ADDITIVE BASED ON BISMUTH TITANATES FOR CEMENT COMPOSITIONS

In Russia, a rapid growth in construction sphere is observed, which by the end of 2023 amounted to 110 million 438.5 thousand square meters. m. housing, which is 7.5% more than a year earlier. The construction process is carried out using high-tech innovative building materials with unique properties, durability, friendly to the environment and humans. Howev-er, in addition to the advantages, modern building materials should be financially accessible, their application should not lead to an unjustified increase in the cost of the project. In this article, the authors analyze the economic efficiency of using a ployfunctional additive based on the TiO2-Bi2O3 oxide system in order to create concrete mixtures, self-cleaning cement plasters, grout solutions for ceramic tile resistant to fouling by microscopic mold fungi. As a result of the research, the authors concluded that a polyfunctional additive based on the TiO2-Bi2O3 oxide system can be used to obtain a wide range of building materials.
