The findings of a research on current challenges of protecting building materials and structures against the impacts of aggressive environments are presented in this monograph. There is a further need for systematic study and their usage in the manufacturing of Portland cement in conjunction with the possibilities of generating new construction materials with greater resilience in demanding conditions using secondary raw materials and wastes from industrial companies. In this regard, in comparison to mining company dump deposits, concentration tailings of ferrous and non-ferrous metals are promising in terms of composition and reserves of valuable components. Tens of millions of tonnes of "tailings" rich in Al2O3, Fe2O3, and other minerals are produced at AGMK's concentration plants. Every year, significant components for the manufacturing of cement, generated during the enrichment of lead and copper-bearing ores, are dumped into landfills. The monograph covers the findings of research into the use of tailings from the Almalyk Mining and Metallurgical Combine's lead concentration and copper smelting facilities as an active mineral addition in the manufacturing of sulfate-resistant Portland cement. In the presence of lead-copper active mineral additives, the impact of mineralogical compositions of clinkers from cement factories in Uzbekistan on the phase composition and qualities of the resulting sulfate-resistant cement is investigated. The importance of additives in building strength and constructing the structure of a cement stone has been demonstrated.
