Method for preparing ultra-high performance concrete by utilizing industrial solid wastes
The invention discloses a method for preparing ultra-high performance concrete by utilizing industrial solid waste, and relates to the technical field of new materials, the ultra-high performance concrete is prepared from the following components in parts by weight: 25-30 parts of PO52.5 common silicon hydrochloric acid cement, 4-6 parts of silica fume, 2-3 parts of first-grade fly ash, 12-15 parts of quartz sand powder, 7-10 parts of admixture, 18-23 parts of quartz sand, 9-11 parts of waste rock fine aggregate, 6-7 parts of water and 5-7 parts of steel fiber. A polycarboxylate superplasticizer and a defoaming agent; the addition amount of the polycarboxylate superplasticizer is 2-4% of the total addition amount of the cement, the silica fume, the fly ash and the admixture, and the addition amount of the defoaming agent is 0.02-0.05% of the total addition amount of the cement, the silica fume, the fly ash and the admixture. The prepared ultra-high performance concrete is high in solid waste doping amount and high in strength, the waste recycling rate is effectively increased, and the production cost of the ultra-high performance concrete is reduced.
本发明公开了一种利用工业固废制备超高性能混凝土的方法，涉及新材料技术领域，按重量份计，由如下组分组成：P•O52.5普通硅盐酸水泥25‑30份，硅灰4‑6份，一级粉煤灰2‑3份，石英砂粉12‑15份，掺合料7‑10份，石英砂18‑23份，废石细骨料9‑11份，水6‑7份，钢纤维5‑7份，聚羧酸减水剂与消泡剂；聚羧酸减水剂添加量为水泥、硅灰、粉煤灰、掺合料的添加总量的2‑4%，消泡剂添加量为水泥、硅灰、粉煤灰、掺合料的添加总量的0.02‑0.05‰。本发明制备的超高性能混凝土固废掺加量高，强度大，有效提升了废弃资源化率，降低超高性能混凝土的生产成本。
