The monograph presents the results of a study on topical issues of protection of building materials and structures from the effects of aggressive environments. In connection with the possibility of creating, on the basis of secondary raw materials and wastes of industrial enterprises, the production of new building materials of increased resistance in aggressive environments, there is a further need for systematic research and their use in the production of Portland cement. In this regard, the tailings of concentration of ferrous and non-ferrous metals are promising in terms of the content and reserves of useful components in comparison with the dump deposits of mining enterprises. At the concentration plants of AGMK, tens of millions of tons of "tailings" rich in Al2O3, Fe2O3, etc. are thrown into dumps annually, which are valuable components for the production of cement, formed during the enrichment of lead and copper-bearing ores. The monograph presents the results of research on topical problems of the use of tailings from the lead concentration and copper smelting factories of the Almalyk Mining and Metallurgical Combine in the production of sulfate-resistant Portland cement as an active mineral additive. The influence of mineralogical compositions of clinkers of cement plants in Uzbekistan on the phase composition and properties of the obtained sulfate-resistant cement in the presence of lead-copper active mineral additives is analyzed. It is shown that additives play an important role in creating strength and forming the structure of a cement stone.

Acceleration of the process of hydration and hardening of sulfate-resistant cement is observed from a change in the mineralogical composition towards a decrease in the content of tricalcium aluminate and a decrease in the basicity of clinker due to high-silica waste, which meets the requirements for sulfate-resistant cements.

The monograph is of interest to scientific and engineering workers of research organizations in the building materials industry and the construction industry, teachers, masters and bachelors of technical universities.
