High Temperature Properties of Geopolymeric Ceramic


Article Preview

With fly ash, metakaolin, slag and alkaline activator as raw materials, the geopolymeric ceramic was synthesized and the properties, such as the weight loss, compressive strength and the structures, at high temperatures of 400~1200°C were measured. The weight loss is in the range of 8~13% from 400°C to 800°C. Comparing with the strength at room temperature, the compressive strength of samples is mostly increased at 400°C and all of them increased at 800°C. 9.65~28.32% strength declines at 1200°C. The variation of the compressive strength with temperature is explained based on the analyses of the phases constitutes and the thermal properties of samples.
