Structure of the products formed in hydrosilicate-producing hardening of porous concrete with sulfoaluminoferrite additives

The effect of the modifying sulfoaluminoferrite (SAF) additive on the composition and structure of the products formed in the process of hydrosilicate-producing hardening of porous autoclaved concrete was investigated. The possibility of intensification of crystallization processes through formation of aluminum- and iron-exchanged calcium hydrosilicates and iron-exchanged ettringite-like compounds.
