Building envelope with the use of cement-free foam concrete
The paper presents the results of research of obtaining cement-free monolithic foam concrete on the basis of activated industrial wastes: granulated blast-furnace slag and nepheline slime. The kinetics of reduction in size of waste products in the rotary-pulsation apparatus is studied, the mechanism of hydration and structure formation of activated binder composition (BC) is revealed, the optimal composition of BC from a standpoint of strength and thermal and physical characteristics is determined. It is shown that the obtained monolithic foam concrete has high operational performance and can be recommended for use in the energy-efficient building envelope.
