摘要
采用机械强化法对再生粗骨料进行多次整形获得机械强化再生粗骨料,并与简单破碎再生粗骨料进行对比性试验,试验测试了不同的胶凝材料用量、不同种再生粗骨料取代率、统一的砂率、聚羧酸高效减水剂、制备的强化再生骨料与简单再生骨料对再生混凝土的力学性能影响。
The recycled coarse aggregate was shaped many times by using mechanical reinforcement method and it resulted in mechanically reinforced recycled coarse aggregate,a comparative test with the simply crushed recycled coarse aggregate was carried out,the effects of different cementing material consumption,replacement ratio of different kinds of recycled course aggregate,unified sand ratio and the polycarboxylate superplasticizer,the prepared reinforced recycled coarse aggregate and the simply recycled aggregate on mechanical properties of recycled concrete were tested.
