The effect of hydrothermal treatment time on the synthesized of Xonotlite using glass cullet (GC) and Calcium hydroxide

Abstract

In this study, the effect of hydrothermal temperature of glass cullet (GC) and Ca(OH)2  was study. The batch-mixed sample with the Ca/Si 1.0 were hydrothermal reacted at different temperature such as 100, 150 and 180oC for 48 hour to find the suitable temperture to form the xonotlite. The data indicate that at 180oC for 48 hour, the peak of xonotlite at 2theta of 30 degree is highest, thus suggest for further study on the effect of hydrothermal reaction time to form the xonotlite.
