再生混凝土圆柱体与立方体抗压强度研究

Study on the Relationship between Cylinder and Cube Compressive Strength of Recycled Aggregate Concrete

本文设计并完成了相关试验,对再生混凝土圆柱体与立方体抗压强度的关系进行了研究。探讨了普通混凝土圆柱体与立方体抗压强度关系式对再生混凝土的适用性,结果表明普通混凝土圆柱体与立方体抗压强度的关系式不适用于再生混凝土。在此基础上,结合本文及已有文献中的试验数据,建议了再生混凝土圆柱体与立方体抗压强度的换算关系式,建议式计算结果与试验结果吻合良好。

This paper deals with the relationship between the cylinder compressive strength and cube compressive strength of recycled aggregate concrete. A test program was carried out to investigate the cylinder and cube compressive strength of recycled aggregate concrete. The applicability of the relationship between the cylinder compressive strength and cube compressive strength for normal concrete when used for recycled aggregate concrete. Finally, based on the test data in this study and that in the available literature, a new relationship for the cylinder and cube compressive strength of recycled aggregate concrete is proposed, which is good agreement with the test data.
