再生废砖粗骨料混凝土基本力学性能研究

Experimental research on the basic mechanical properties of recycled waste brick coarse aggregate concrete

进行了再生废砖粗骨料混凝土基本力学性能的试验,主要研究了与普通混凝土强度等级相同条件下再生废砖粗骨料混凝土的立方体抗压强度、轴心抗压强度、劈裂抗拉强度、弹性模量。试验结果表明:再生砖粗骨料混凝土的立方体抗压强度、轴心抗压强度、劈裂抗拉强度、弹性模量均要低于普通混凝土,其主要原因可能为再生砖粗骨料强度较低;再生砖粗骨料混凝土的立方体抗压强度、轴心抗压强度和劈裂抗拉强度与普通混凝土的破坏形式相类似。

The experiments on the basic mechanical properties of recycled waste brick coarse aggregate concrete are completed.The cu-bic compressive strength, axial compressive strength, the splitting-tensile and elastic modulus are analyzed.It is proved that the cubic com- pressive strength,axial compressive strength,the splitting-tensile and elastic modulus of recycled waste brick coarse aggregate concrete was reduced than ordinary concrete.The destruction of the cubic compressive strength, axial compressive strength and the splitting-tensile were similar between recycled waste brick coarse aggregate concrete and ordinary concrete.
