Abstract: Experimental data on strengthening of foam glass materials is presented. A new mechanism of strengthening is proposed which involves formation of amorphous matrix nanoglobules. Highlights: nanospheroid occurrence in foam glass; new strengthening mechanism of amorphous materials; correlation between micro-structural changes in the interpore partition of porous materials and mechanical characteristics thereof.

Abstract: nsulating glass foam (IGF) was successfully fabricated by wet process. The starting proportion of 65 wt% waste glass, 12 wt% slag, 23 wt% commercial soap was added with 15 wt% Na₂SiO₃ and represented then was sintered at 725 °C. The IGF had cellular structure with the macro-pore size at 0.428 mm and thin cell walls. Density, thermal conductivity and compressive strength were 0.310 g/cm³, 0.130 W/m.K and 0.78 MPa, respectively. The average pore diameter and porosity increased with increasing the Na₂SiO₃ concentration and the sintering temperature. On the other hand, the density, thermal conductivity and compressive strength were decreased.
