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.
