Abstract

Abstract A glass foam (GF) of high specific compressive strength (12.17±1.91 MPa g −1 cm −3 ) and low thermal conductivity (.121±.001 Wm −1 K −1 ) was produced from waste glass of photovoltaic module, eggshells, and bentonite clay. The influences of the amount of clay and heat‐treatment temperature on the GFs final properties were assessed. X‐ray diffraction results and the data of microscopic analyses demonstrated that addition of clay affected the structure and porosity of the GFs, and consequently their mechanical properties. On the basis of the mechanical property (density), the GF that composed of 80% waste glass, 10% clay, and 10% eggshell at the sintering temperature of 900°C was the best. The GFs reported in this study could serve as promising insulators in situations where high load support is required.
