研究了石灰石、矿渣、烧页岩及粉煤灰四种混合材复配对水泥及混凝土性能的影响。试验结果表明,矿渣和石灰石有益于改善水泥的标准稠度用水量、外加剂相容性、混凝土的工作性能及强度,而烧页岩和粉煤灰有益于水泥的强度,几种混合材的合理搭配可以改善水泥和混凝土的性能。 The effect of four kinds of mixture of limestone, slag, shale and fly ash on the properties of cement and concrete was studied. The test results show that the slag and limestone are beneficial to improve the standard consistency water content, admixture compatibility, concrete performance and strength, while burning shale and fly ash are good for the strength of cement, several kinds of mixture is reasonable With can improve the performance of cement and concrete.
