Abstract
In this paper, the utilization of waste glass and fly ash as starting materials to prepare foam glass was studied. First, the result from TG–DTG revealed the appropriate foaming temperature was around 950°C. And then, foam glass was prepared which using waste glass and fly ash as starting materials, as well as SiC as foaming agent at 950°C for 20min successfully. The results show that the volume expansion multiple of the sample foamed at 950°C for 20min is 5.81 compared with the green body. X-ray diffraction revealed the peaks intensity of the observed phases decreased with the increase of temperature. The foam glass had a bulk density of 267.2kg/m3, a compressive strength of 0.9829MPa, and a porosity of 81.55%.
