MODIFIED AERATED CONCRETE BASED ON MAN-MADE WASTE

This article presents the results of experimental studies on aerated concrete based on industrial waste with improved operational, physical, chemical and mechanical properties; modified homogeneous structures are obtained in this material as a result of its compaction and hardening. The structure of the modified aerated concrete and its influence on the physical, mechanical and hydrophysical properties are studied in detail. Aluminium powder is used as a foaming agent. The content of active aluminium is 82%. To give the powder hydrophilic properties, it is treated with an aqueous solution of surfactants. The use of complex organometal modifiers in products made of modified and non-autoclaved aerated concrete with industrial waste, such as phosphogypsum, significantly increases the likelihood of obtaining high-quality products by controlling the processes of gas evolution and structure formation under the impact of the organometal modifier.
