普通混凝土与再生混凝土抗压强度尺寸效应对比研究

经济的快速发展需要强大的资源储备支撑,混凝土的大量需求导致了天然砂石趋于枯竭,再生混凝土可以很好的解决这一难题,但再生混凝土的尺寸效应问题目前研究甚少。本文主要对比分析了普通混凝土立方体与棱柱体的抗压强度尺寸效应,以及不同骨料取代率的再生混凝土抗压强度尺寸效应之间的联系,并总结了目前的主要数值模拟方法。

The rapid development of economy needs strong support of resources reserves,a large amount of consumption of concrete causes the natural sandstone dries up,recycled concrete can well solve this difficult problem.Size Effect of recycled concrete problem is still little researched,this paper mainly analysises size effect of the common concrete cube and prism compressive strength as well as the connection between different aggregate replacement rate,summarize the current major methods of numerical simulation in the meantime.
