Abstract: The influence of high alumina dusting micropowder on the properties of low cement castables was studied. The specimens were demolded after natural curing for 24 hours, then dried at 110 °C for 24 hours and heat-treated at 1100 °C for 3 hours. The bulk density, room temperature flexural strength and room temperature compressive strength of the specimens after heat treatment at 110 °C and 1100 °C were measured. The results show that the addition of an appropriate amount of high alumina dusting micropowder can improve the properties such as the bulk density and room temperature strength of low cement castables, and the suitable addition amount is 5% (mass fraction).
