Investigations of cement composite with expanded glass filler at high temperatures

Abstract

Lightweight refractory composite with expanded glass filler, calcium aluminate cement, additives of metakaolin waste, microsilica and hybrid deflocculants were investigated. The microstructure analysis were performed by using the scanning electron microscope. In addition, the thermal shock resistance, physical and mechanical properties of the composite were deter.ined. Significant changes in microstructure of the composite was caused after firing at the temperature of 1000°C when the expanded glass filler was melted.
