The article deals with the main trends in the production and application of silicate bricks in modern construction. It describes its positive and negative properties, the main of which are its high average density and high thermal conductivity, which is accompanied by losses of heat through the enclosing walls of buildings and structures. The possibility of improving the thermal-technical characteristics and reducing the density of this type of walled products by using ash microspheres is considered. Characterization of ash microspheres, which are a component of ash and slag wastes of thermal power plants is given. They have a number of valuable properties: low density, closed microporosity, favorable chemical-mineralogical composition, presence of amorphous silicate glass wool phase, which causes active interaction with lime under conditions of elevated temperatures and pressure. The article gives the data on the influence of the content of the calcareous component and the specific pressing pressure on the properties of the products obtained and the features of their microstructure. The results of semi-industrial tests are presented.
