This paper presents a comprehensive experimental study of thermal properties of various alkali-activated binders at ambient and elevated temperatures. The binders were prepared using alkali-activated low calcium fly ash/ground granulated blast-furnace slag at ratios of 100/0, 90/10, 50/50 and 0/100 wt%. These binders can be considered as a composite of solid, water and air. Accordingly, a three-phase...
This paper reports on the high-temperature performance of cementitious materials containing fine glass powders (GP) as a partial replacement for ordinary Portland cement. Various mixes were prepared in which cement was replaced by GP in 3 different proportions, i.e., 5 wt%, 10 wt% and 20 wt%. Compressive strength tests were carried out at various temperatures (20, 500 and 800 °C) for mortars containing...
