The use of the ash of thermal power plants for the production of efficient porous insulation

Abstract

The article presents the results of research related to the use of ash from thermal power plants for the production of porous heat insulating materials. Using the method of differential - thermal analysis, the optimal values of the composition of the raw mix and the thermal regimes of the formation of the porous structure were found. It is shown that it is possible to obtain a new ash-based binder and thus replace up to 70% of cement in the production of thermal insulationthe properties of the new material are similar to the properties of foam concrete.
