Abstract
The possibility of using granite siftings from the Mikashevichi Deposit in the Republic of Belarus for production of porous heat-insulating materials was investigated. The initial glasses were synthesized with from 50 to 70% (by weight) granitoids and additional incorporation of quartz sand, chalk, and soda. The region of compositions with the necessary viscosity at foaming temperatures of 800 and 830°C was determined. Foam glass with a bulk density of 180–190 kg/m3, compressive strength of 0.72–0.78 MPa, and heat conduction of 0.091 W/(m · K) was fabricated with these compositions. The possibility of manufacturing foam glass by adding up to 60% of inexpensive natural raw material to the batch was demonstrated.
