摘 要: | 分别对7 d、28 d、60 d龄期的不同再生粗骨料替代率混凝土进行了抗压强度试验,分析了再生骨料混凝土破坏形态及不同再生粗骨料替代率对再生混凝土抗压强度的影响,并对其原因进行了分析.试验结果表明28 d龄期的再生骨料混凝土强度能够达到标准要求,用再生骨料配置混凝土是可行的.

Experimental Study on Compressive Strength of Recycled Aggregate Concrete with Different Replacement Ratios |
| |
Abstract: | Compressive strengths of recycled aggregate concrete with different recycled aggregates replacement ratios at 7 d,28 d,60 d ages are investigated respectively.Failure process and failure mode of RAC are analyzed.The influences on compressive strength with same mix ratio and different RA replacement ratios are also analyzed.And the reason is investigated in this paper.The experimental results indicate that compressive strength of recycled concrete at 28 d age can reach the standard generally,it is feasible to mix concrete with recycled aggregates. |

Keywords: | recycled aggregates(RA) recycled aggregate concrete(RAC) recycled aggregate replacement ratio compressive strength |
