摘　　要：分析了湖北荆门地区砂岩的化学成分、亚甲基蓝值及矿物组成,以砂岩作为混合材试验制备复合硅酸盐水泥,分析了不同种类及不同掺量砂岩对水泥标准稠度、凝结时间及力学强度的影响,验证了砂岩作混合材生产复合硅酸盐水泥的可行性。在以砂岩作混合材生产复合硅酸盐水泥时,需选取适合类别的砂岩,同时严格控制砂岩掺量,当砂岩掺量达到3%~4%时,将难以满足工程施工要求。The chemical composition,methylene blue value,and mineral composition of sandstone in the Jingmen area Hubei province were analyzed.The sandstone is used as admixture to produce composite Portland cement.The effect of different type and ratio sandstone on cement consistency,setting time and strength were studied.The feasibility of sandstone as admixture in composite Portland cement is verified.The results show that the type and ratio of sandstone should be strictly selected and controlled in composite Portland cement,and the appropriate dosage of sandstone is 3%~4%,otherwise cement will be difficult to meet the requirements of engineering construction.
