| 中文摘要: |
| 采用硅烷偶联剂KH-550溶液浸泡陶瓷再生粗骨料,改变其表面性能,从而增强陶瓷骨料-水泥石界面的粘结性能。使用处理后的陶瓷骨料制备陶瓷再生混凝土,并对其进行了立方体抗压强度试验和弹性模量测试。结果表明：随着陶瓷粗骨料掺量的增加,再生混凝土的强度降低;当掺量为60%时,再生混凝土的弹性模量较原碎石混凝土提高了3.2%;当掺量为100%时,再生混凝土抗压强度仍然满足要求。 |
| 英文摘要: |
| Ceramic recycled coarse aggregate was soaked with silane coupling agent (KH-550) solution to improve its surface properties and then enhance bonding properties of interface between ceramic aggregate and cement. Using above-treated ceramic aggregate to prepare recycled aggregate concrete, cube compressive strength test and elasticity modulus measurement were conducted. Results show that the compressive strength of ceramic recycled aggregate concrete decreases significantly along with the increase of ceramic coarse aggregate content. When its content is 60%, elasticity modulus of recycled concrete is improved by 3.2% compared to that of original rubble concrete; when the content is 100%, the compressive strength of recycled concrete still meets the demand. |
