摘　　要：收集废旧陶瓷制成再生粗骨料,按照质量替代天然碎石,研究了再生粗骨料对混凝土力学性能的影响,并与普通混凝土力学性能进行对比分析。结果表明:配合比相同的情况下,随着陶瓷再生粗骨料替代率的增加,混凝土抗压强度先降低后增加,而混凝土的抗折强度逐渐降低。因此,用废旧陶瓷再生粗骨料替代天然碎石制备混凝土是可行的。The effect of recycled coarse aggregate on the mechanical properties of concrete was studied by collecting the waste ceramic to make recycled coarse aggregate and replacing natural crushed stone by equal quality. The results show: with the increase of replacement rate of ceramic recycled coarse aggregate, the compressive strength of concrete decreases at first and then increases, while the flexural strength decreases gradually. This indicate that it is feasible to prepare concrete with recycled coarse aggregate instead of natural crushed stone.
