摘要
为了解再生粗骨料对混凝土基本性能的影响,通过再生粗骨料混凝土与普通混凝土在工作性、立方体抗压强度,抗氯离子渗透性及收缩率方面的对比试验得出结论:与普通混凝土相比,再生粗骨料混凝土的力学性能和耐久性稍低,但通过优化配合比设计可以达到与普通混凝土相近的水平。
In order to study the effect of recycled coarse aggregate on the basic performance of concrete,we carded out comparison test between the recycled coarse aggregate concrete and ordinary concrete in cube compressive strength, resistance to chloride ion permeability and shrinkage rate,we could get the conclusion that the recycled coarse aggregate concrete was slightly lower than ordinary concrete in mechanical properties and durability,but we could achieve the similar performance with ordinary concrete by the design of mix proportion.
