Fiber-reinforced recycled aggregate pervious concrete
The invention discloses fiber-reinforced recycled aggregate pervious concrete, which is prepared by adopting the following formula: 270-350 kg/m < 3 > of cement, 355-450 kg/m < 3 > of water, 1360-1950 kg/m < 3 > of coarse aggregate, 35-100% of recycled aggregate, 0-30 kg/m < 3 > of polymer emulsion, 0-9.6 kg/m < 3 > of water reducing agent, 0-5 kg/m < 3 > of high-performance admixture, a water-binder ratio of 0.24-0.42, a slurry-bone ratio of 1: 3.8-1: 4.7, the maximum nominal particle size of the coarse aggregate is 5-20 mm, the maximum nominal particle size of the recycled aggregate is 5-20 mm, and the maximum nominal particle size of the recycled aggregate is 5-20 mm. The pervious concrete is prepared from the recycled aggregate, carbon emission in the whole life cycle of ground and pavement paving materials is further reduced, meanwhile, construction waste and solid waste are effectively utilized, the breaking strength and toughness of a pervious paving layer are greatly improved through the fiber reinforcement technology, a premixing mode is adopted for production in a breakthrough mode, the production efficiency is greatly improved, and the production cost is reduced. And the quality stability of a pervious concrete product is ensured to a greater extent.
本发明公开了一种纤维增强再生骨料透水混凝土，所述混凝土采用以下配方制成：水泥270‑350kg/m3和355‑450kg/m3，水100‑155kg/m3，粗骨料1360‑1950kg/m3，再生骨料占比35%‑100%，聚合物乳液0‑30kg/m3，减水剂0‑9.6kg/m3，高性能外加剂0‑5kg/m3，水胶比0.24‑0.42，浆骨比1:3.8‑1:4.7，粗骨料最大公称粒径5‑20mm，通过再生骨料制备透水混凝土，进一步减小地面和路面铺装材料全生命周期的碳排放，同时有效利用了建筑垃圾和固废，通过纤维增强技术，极大地提升了透水铺装层的抗折强度和韧性，突破性地采用预拌方式生产，极大地提高了生产效率，更大程度上确保了透水混凝土产品的质量稳定性。
