【 摘 要 】

Alkali activated materials have shown potential for use in high temperature applications. This paper deals with thermal behaviour of various inorganic polymer formulations, which were prepared by mixing metakaolin, blast furnace slag, fly ash and cement kiln dust as alkaline activator. The cement kiln dust was added in the amount of 10 wt.%. The influence of thermal treatment ranging from 30 to 1000°C on the following characteristics was evaluated: compressive strength, thermal expansion, weight loss, melting point, morphology changes and dehydration. The thermal behaviour was studied by TG-DTA analysis, dilatometry and heating microscope, XRD analysis was used to examine phase changes. All measurements were conducted on samples after 28 days of curing time.
