陶瓷粗骨料对再生混凝土力学性能的影响

Effect of Ceramics Coarse Aggregate on Mechanical Properties of Recycled Concrete

文中研究了陶瓷粗骨料替代率为0、40%、80%、100%的混凝土基本力学性能的影响。试验结果表明,随着陶瓷粗骨料替代率增大,混凝土试块破坏面积更大、保护层脱落更加明显,混凝土呈现更为明显的脆性;混凝土试块的抗压强度、初始刚度以及弹性模量都会随之降低。

In this experiment,the effect of ceramics coarse aggregate on the basic mechanical properties of concrete with substitution rate of 0,40%,80%and 100%was studied.The test results show that with the increase of the substitution rate of ceramics coarse aggregate,the damage area of concrete cube was larger and the protective layer falls off more obviously,concrete failure is more pronounced brittleness.the compressive strength of the compressive strength,initial stiffness and Elastic modulus of the concrete cube would decrease.
