水泥对半刚性路面混凝土力学性能影响研究

针对水泥对半刚性路面混凝土力学性能的重要影响,按照混凝土力学性能试验方法,对半刚性路面混凝土抗压强度与模量、抗折强度与模量及劈裂抗拉强度等力学指标进行研究。结果表明,水泥用量的较小变化极大影响混凝土的力学性能。针对水泥的无机水硬性胶凝材料特点,通过微观试验,进一步解释了水泥在半刚性路面混凝土强度形成中的作用,并归结为4个方面。

Influence of Cement on Mechanical Performance of Semi-Rigid Pavement Concrete

To counter important influence of cement on mechanical performance of semi-rigid pavement concrete,on the basis of testing methods of concrete mechanical performances,mechanical performance indexes are studied,such as compression strength and compression module,flexural strength and flexural module and splitting tensile strength.The results indicate minor changes of cement dosages have great influences on concrete mechanical performances.In accordance with the binder characteristics of cement,the function of cement in semi-rigid pavement concrete strength formation with micro test is interpreted and four conclusions are drawn.
