采用选择性溶解法和非线性拟合法分别测量了煤矸石-矿渣-水泥三元体系中三种原材料（煤矸石，矿渣，水泥）的水化进程，并对含有不同掺量矿物掺合料的复合水泥浆体干燥收缩及抗压强度进行了测量和分析。结果表明：当复合水泥浆体中含有5％煤矸石，25％矿渣时，复合材料的干燥收缩较小，抗压强度较大。
Selective dissolution method and nonlinear fitting method were used to measure the hydration degree of three raw materials ( coal gangue , slag and cement ) in coal gangue-slag-cement ternary blended systems , respectively .The drying shrinkage and compressive strength of pastes which incorporated with coal gangue and slag of different mix proportions were determined and analyzed .The results show that the blended cement paste containing 5%coal gangue and 25% slag can meet the composite material which has small drying shrinkage , high compressive strength .
