偏高岭土对混凝土的工作性、粘聚性、强度 和吸收性的水泥等效性
摘要
混合物进行性能测试。结果表明，添加 20%的MK作为普通硅酸盐水泥（OPC）的替代物，能最好地提高 28天和 70
天的立方体强度，而添加 30%的MK作为OPC的替代物，总是能提高粘聚性和降低吸收性，但会损害工作性。此外，
本文还评估了水泥当量系数（CEF），即每添加一质量的MK所对应的OPC的当量质量，包括工作性和粘聚性的性能
属性。虽然MK的实际 CEF在较高的W/CM比率下通常较高，在较高的MK含量下较低，但总体而言，发现坍落度、
流动性、粘聚性、28天立方体强度、70天立方体强度和吸收系数的平均 CEF分别为 1.98、2.17、3.83、1.93、2.12和
4.70。这些 CEF值表明，MK是一种高效的胶凝材料，可以提高粘聚性、强度和耐久性。此外，事实证明，工作性和
粘聚性的 CEFs是帮助MK混凝土混合设计的有用参数。
