| 摘 要： | 通过对再生骨料和天然骨料的级配、压碎指标、吸水性等基本性能进行对比试验,研究了再生骨料的基本性能以及对再生混凝土配合比设计的影响,讨论了再生混凝土配合比的设计方法.试验结果表明,本实验采用基于再生骨料预吸水的配合比设计方法配置的混凝土拌和物的坍落度和28 d立方体抗压强度,完全符合现行规范要求.这也表明再生骨料可以部分或全部代替天然骨料来配制混凝土.

| Abstract: | Through the test study of basic performances of recycled aggregates and natural aggregates,such as recycled aggregate ratio,crushed index,water-absorbing property,etc.,the influence of recycled aggregates to the mix proportion design of recycled aggregate concrete is studied and the proportion design methods of recycled aggregate concrete are discussed.Test results show that the slump and the cube compressive strength within 28 days of recycled concrete made with the proportion design of recycled aggregate ... |
