水泥砂浆搅拌法对混凝土性能的影响

摘要

在两种不同搅拌工艺(普通法和水泥砂浆法)下,分别对C20、C30、C40三种普通水泥混凝土的和易性、抗压、抗折强度、耐磨性及抗渗性进行试验测试,并对其结果进行分析研究,经对比分析,水泥砂浆法搅拌工艺主要可通过提高水泥石与集料粘结力及改变内部孔隙分布提高混凝土的强度和抗渗性.%In two different mixing process (general method and cement mortar method),respec-tively workability,compressive strength, flexural strength, wear resistance, permeability resistance of three kinds of ordinary cement concrete(C20,C30,C40) were tested respectively,and the results were analyzed and studied,by comparative analysis,cement mortar method can improve the strength and impermeability of concrete through improving the bond strength between cement and aggregate,and changing the distribution of the internal pore.
