Cover Story: Aqueous suspensions of soda lime glass and coal fly ash were activated with NaOH (3M). Despite the relatively low molarity (compared to geopolymer-yielding mixtures), the suspensions underwent gelation and presented a marked pseudoplastic behaviour. A significant foaming could be achieved by air incorporation, in turn resulting from intensive mechanical stirring (with the help of a surfactant), before complete hardening. Dried foams were later transformed, by heat treatment at 700-900 °C, into porous glass-ceramics, exhibiting a remarkable crushing strength (6 MPa, with a porosity of about 70%) and a low thermal conductivity, coupled with good stabilization of pollutants from the starting waste.
