摘　　要：用红外光谱、X射线衍射和扫描电子显微等现代微观微区测试手段 ,对高炉矿渣及含硫高的矿山尾矿砂混合体系的水化反应过程进行检测和分析 ,了解这一过程中新、旧物相的变化情况 ,通过对主要新生相钙矾石的生长和生成量的检测 ,选出理想的激发剂和合适的养护时间 ,从而给出以高炉矿渣作粘合剂 ,以富硫尾矿砂作骨料研制新型建筑材料的具体工艺条件。In the mixture with sulphur-rich tailings, the hydration reaction of blast-furnace slag has been studied by IR, XRD and SEM in order to understand the formation dynamics of ettringite. The results show that the quantity of ettringite is related to chemical admixture and curing time which is better for 30 days and the mechanical strength of the sample in which there are more ettringite is quite good.
