| 摘 要： | 通过试验测出再生粗骨料的堆积密度、级配、吸水率、压碎指标等,参照《普通混凝土设计规程》,采用附加水法,实验室配制C30再生混凝土,再生粗骨料取代率为0%,25%,50%,75%,100%。试验结果表明,随再生粗骨料取代率的增大,立方体28 d抗压强度逐步降低,但是都能满足C30强度等级要求。

| Abstract: | Based on tests, the paper identifies the bulk density, gradation, water absorption, and crushing index, adheres to the Design Regulation of Common Concrete, adopts the additional water method to have C30 recycled concrete, and the replacement rate of the recycled coarse aggregate can be 0%, 25%, 50%, 75% and 100%, and concludes by the tests that the cube 28 d compressive strength reduces gradually along with the increasing replacement rate of the RAC, but they can meet the demand of C30 strength grade. |
