Abstract

In this paper, variations of loss factor and storage modulus of Alkali-Activated Composite cementing materials (AAC) made from slag and fly ash and Ordinary Portland Cement (OPC) were studied at the temperature rising period from 40 to 200 by using Dynamic Mechanical Analyzer (DMA). The study showed that, compared to OPC, the dynamic properties of AAC were affected significantly by temperature and its loss factor increased gradually with the temperature, also, the variation of loss factor was larger than that of OPC. The storage modulus of both ACC and OPC was affected significantly by the temperatures and showed a similar change trend. With the temperature rising, the storage modulus reduced first and then tended to be stable. During the temperature rising, the flexural strength of AAC had a great loss.
