THE FACADE SILICATE COMPOSITION ON THE BASIS OF THE WASTE CELLULAR GAS SILICATE

The article presents a study of facade silicate composition created on the basis of autoclaved silicate aerated concrete waste. The method of processing of aerated concrete production waste based on grinding them to a fine-dispersed state is described. The finely dispersed waste of aerated concrete production was used in building materials as a substitute for ex-pensive components such as white Portland cement. The developed composition is characterized by processability, economy and improved performance characteristics. The developed facade silicate composition has high vapor permeability, water resistance and heat resistance up to 500 °C. This composition has good adhesion to mineral substrates, weather resistance and durability. The paper presents the results of physicochemical analysis confirming the formation of strong compounds based on calcium hydrosilicates and hydrogranates in the structure of the material. The obtained results open prospects for the creation of environmentally sustainable building materials based on recycling of waste cellular concrete.
