- 摘要:
- 为研究废弃玻璃与粉煤灰在自密实再生混凝土中的最佳取代率,在再生粗骨料取代率为20%的基础上,利用废弃玻璃取代天然细骨料(比例分别为0%、10%、20%、30%),同时等梯度增加粉煤灰取代水泥的比例(分别为20%、30%、40%).通过测定混凝土坍落扩展度判定混凝土的流动性,并测定混凝土的7、14、28、56 d抗压强度.试验结果表明,当废弃玻璃与粉煤灰的最佳取代率分别为20%和30%时,自密实再生混凝土的力学性能和经济性达到最佳.
- Abstract:
- In order to study the optimal substitution rate of waste glass and fly ash in selfk-compacting recycled concrete, the paper substitutes the rate of replacement of natural fine aggregate by 20% on the basis of controlling the replacement ratio of recycled coarse aggregate to 0%, 10%, 20%, 30%. At the same time, the proportion of fly ash instead of cement is equal to 20%, 30%, 40%. The fluidity of concrete was determined by measuring the slump expansion of concrete and the compressive strength of concrete at 7 d, 14 d, 28 d and 56 d was measured. The experimental results show that: when the optimum substitution rates of waste glass and fly ash are 20% and 30%, respectively, the mechanical properties and economic performance of recycled concrete from the close chamber are optimal.
