| 摘 要： | 充分利用尾矿废石做骨料,代替部分细骨料,全部替代粗骨料,使用聚羧酸高效减水剂与脂肪族(羟基)磺酸盐高效减水剂复合的外加剂来制备自密实混凝土。结果表明:自密实混凝土的各种性能良好,不仅减少了水泥用量,降低了自密实混凝土的成本,且大掺量使用尾矿废石,对发展我国低碳经济、循环经济、节能减排有着重大意义。 |
| 关 键 词： | 自密实混凝土 尾矿废石 工程应用 |

| Abstract: | Making use of tailings waste rock,admixture mixed with polycarboxylate superplasticizer and aliphatic(hydroxy)sulfonate super-plasticizer,to prepare self-compacting concrete,tailings waste rock are substituted for part of fine aggregate and all coarse aggregate.The results show that self-compacting concrete with good performance,is not only reduced the amount of cement,but also reduced the production cost.It is significant for the development of low-carbon economy,recycling economy,energy saving and emissio... |
