Investigation of foamed glass using natural waste materials as foaming agent

The use of high-quality thermal insulation materials to improve the energy efficiency buildings is strongly increasing. Foam glass, a durable and porous material that resistant almost all substance effects, one best materials. Glass foaming complicated process affected by types agents used in initial composition mixture mode foaming. influence components - glass matrix agent discussed this paper. Three powder (alkali frit, soda-lime silicate borosilicate) were determined be material. generate gas phase via decomposition eggshell or chemical reaction with oxygen molten SiC coffee ground waste. compacts fired at 900 °C for 10 minutes content 2 wt % presented excellent properties using mixtures. waste-glass mixtures show inferior each different powder.
