摘要

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 ℃. 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 ℃ for 20 min successfully. The results show that the volume expansion multiple of the sample foamed at 950 ℃ for 20 min 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 267.2 kg/m~3, a compressive strength of 0.9829 MPa, and a porosity of 81.55%.
