Аннотация

This article examines the physicochemical properties of expanded clay concrete compositions modified with mineral and chemical additives. In the research process, the influence of additives on the microstructure of cement stone, hydration processes, and the formation of the filler-bonding interface zone (CZ) was analyzed. The results of physicochemical analysis showed that mineral and chemical additives compress the cement matrix, reduce capillary porosity, and increase the structural stability of the interface zone. The obtained results have scientific and practical significance for the creation of energy-saving and high-performance expanded clay concrete materials.
