再生混凝土基本力学性能试验分析

Experimental research on the basic mechanical properties of recycled aggregate concrete

进行了再生混凝土配合比设计,完成了再生混凝土基本力学性能相关试验,并以天然骨料混凝土作为基准进行对比,主要研究了再生混凝土的立方体抗压强度、立方体劈裂抗拉强度、抗折强度的影响因素及变化规律。通过试验数据的统计回归,建立了再生混凝土抗压强度公式,给出了再生混凝土各项强度指标之间关系式。

In this paper, the mix proportion design of recycled aggregate concrete is put through; ex- periments On basic mechanical properties of recycled concrete are completed; using natural aggregate concrete as the benchmark for targeted comparative test, influence factors and law of variation on the cube compression strength, splitting tensile strength and flexural strength of recycled aggregate con- crete are experimental evaluated. Based on the data regression, intensity formula of recycled aggregate concrete is comfirmed throught the experiment, also, relationships between compression strength , tensile strength and flexural strength of recycled aggregate concrete are established.
