This paper presents experimental results on the expansion by Le chaterlier tester and the compressive strength.Hydraulic ash-zeolite （HAZ） cementitious material was blended as the chemical activator to study the effects of the activator on the expansion and the compressive strength.The results show that HAZ can not only deduce the expansion,but it can also make the prisms compressive strength increased obviously.Scanning electron microscope observation and X-ray diffraction analysis indicated that the main hydrated products of the sample are calcium hydroxide,ettringite,zeolite,and calcite,which consistent with the results of the expansion and the strength tests. 固硫渣 安定性 水泥熟料 活性氧化钙 胶凝材料 cycled flulized bed ash（CFBA） soundness cement clinker free CaO cementitious material TQ172.1 武汉大学创新基金资助（205270026） 2005-01-01 2021-04-01 S2
