Glass Foams Containing Fly Ash And Sheet Glass By Adding Calcite As Foaming Agent

Ediz , Ercenk

Glass foam is a porous isolation material used for heat isolation. In this study, the possibilities of glass foam production using calcite as a foaming agent was investigated. The mixture was prepared 10% wt. of waste window glass and 90% wt. Seyitömer thermal power plant fly ash. 2.5 to 10% wt. calcite was added to mixture and pressed under 75 MPa pressure by uniaxial cold pressing to obtain cylindrical specimens. Pressed samples sintered at 750-950 °C temperature range for 1 hour according to differential thermal analysis (DTA) results. The effect of calcite addition and sintering temperature on the porosity, density, compressive strength, microstructure and crystalline phases were investigated. It was determined that the properties of glass foams was changing depend on calcite addition as foaming agent and the sintering temperature. The results showed that calcite provide foaming in specific proportions for glass foam production. Keywords: Calcite, fly ash, glass powder, glass foam
