Effects of Foaming Agent Contents and Firing Temperatures on Porosity and Density of Granulated Foam Glass Prepared from Waste Glass

The purpose of this research work was to analyze production of granulated foam glass (GFG), a lightweight aggregate used in cement concrete, using mixed waste glass as the main ingredient. The effects of foaming agent content and firing temperature on density and porosity of the GFG were studied. Dolomite mineral and tapioca gel were selected as the foaming agent and the binding agent respectively. Dolomite content was varied from 1-4 wt % while the tapioca gel was fixed at 35 wt %. Firing temperatures used were 750 °C and 800 °C for 10 min. It was found that firing at 750 °C was more suitable than at 800 °C as the latter temperature led to non-uniform porosity due to bloating. When increasing the dolomite content, the bulk density of the GFG decreased while the porosity increased. The best condition obtained from this current research was 3% dolomite and 750 °C firing as the GFG showed a desirable bulk density of 0.54 g/cm3 and a porosity of 76% with a uniform pore structure. The pore size of this GFG was mostly found to be in the 10 mm range.
