  • X-ray micro-tomography investigation of the foaming process in the system of a waste glass - silica mud - MnO2
    Ducman, Vilma ...
    In case of foamed lightweight aggregates (LWA), porosity is introduced by the addition of a foaming agent to the glassy matrix, which degasses at an elevated temperature, so that the resulting gasses ... remain trapped inside the glassy structure. The efficiency of action of MnO2 as a foaming agent in wasteglass and waste glass / silica mud systems was studied. Samples were fired at different temperatures and with different dwelling times at a certaintemperature, and the development of porosity was investigated by means of X-ray micro-tomography. It was found that, with the prolongation in dwelling times, the number of pores decreased, while, on the other hand, the volume of these pores increased, and that the addition of silica mud increasesthe foaming temperature and slows down the foaming process.
