Development of compositions of dinas lightweight materials using combinable additives

The results of the development of compositions of dinas lightweight materials based on quartzites using burnable additives, in particular sawdust, coal waste, and a synthesized mineralizer, are presented. A composition of dinas lightweight material with improved physical and mechanical properties has been developed ― with increased porosity and mechanical strength, low density and low thermal conductivity. The developed composition of lightweight silica material can be used for high-temperature thermal insulation, as well as for lining loaded structural units.
