Studies of Heat Insulation Concrete

Abstract

The article analyzes the properties changes of non-autoclave foam on a protein foaming agent with the introduction of dispersed wollastonite and diopside. A decrease in the density of foam concrete (to the grade D300, D400), frost resistance of the material, as well as shrinkage deformations was noted. The optimal technological parameters have been determined, allowing to obtain more stable properties and structure of heat-insulating cement-ash non-autoclave foam concrete. The flow chart of the production of foam concrete of natural hardening in the separate preparation of foam and mortar is presented. The studies were performed at NSTU and NGASU (Novosibirsk) and the NII (Norilsk).
