Building materials are classical composites with heterogeneous and multiphase structure. Components are introduced into their composition - industrial waste. Based on the author's developments, the modification of fine-grained concrete with mineral additives based on industrial waste from the Lower Volga region as hardening activators and fillers of concrete compositions leads to an increase in compressive strength. Fine-grained concrete modified by industrial waste components (construction composition) will be widely used due to its architectural and construction properties, increased physical and mechanical characteristics, versatility and an affordable raw material base in the Lower Volga region, which is economically and environmentally justified. It is concluded that fine-grained concrete modified by industrial waste components (construction composition) is promising at all stages of construction of buildings and structures.
