This article presents the results of a comprehensive study of the structure formation and properties of non-autoclaved foam concrete. The objects of the study were composites based on a wide range of binders: Portland cement CEM I 32.5N, 42.5N, 52.5M, magnesia cement, caustic dolomite, slag-alkali cement, building gypsum, gypsum-alumina expanding cement, and liquid glass. Varying the type of foaming agents (synthetic and protein) and modifying additives (microsilica, potash, calcium chloride, superplasticizer UP-2) made it possible to control the rheology of the mixture and the hardening kinetics of non-autoclaved foam concrete. The possibility of targeted regulation of a wide range of physical and mechanical properties (strength, density, thermal conductivity) and the performance characteristics of the developed compositions was proven theoretically and experimentally. The obtained data confirm the potential of using alternative binders for the production of energy-efficient cellular composite building materials with predetermined properties.
