Steel slag-based pervious concrete
The invention discloses a steel slag-based pervious concrete. The concrete comprises, by weight, 100 parts of steel slag, 15-30 parts of phosphate, 1-5 parts of a retarder and 50-150 parts of steel slag aggregate. When in use, the concrete materials are uniformly stirred and mixed with water, the obtained mixture is formed and naturally cured. The concrete has the excellent properties of high early strength, high low-temperature setting speed, small volume deformation, wide environmental adaptability, good water permeability and the like; and the defect that traditional pervious concrete is low in strength is overcome, meanwhile, a large amount of waste steel slag can be effectively treated, energy conservation, consumption reduction and emission reduction are achieved, and certain environmental protection and economic benefits are achieved.
本发明公开了一种钢渣基透水混凝土，其组成物及重量份为钢渣100份、磷酸盐15‑30份、缓凝剂1‑5份、钢渣骨料50‑150份；使用时该混凝土材料与水搅拌混合均匀，成形，自然养护即可，其具有早期强度高，低温凝结速度快，体积变形小，环境适应性广，透水性能良好等优良性能；本发明克服了传统透水混凝土强度低的缺点，同时可以有效处理大量废弃钢渣，实现节能降耗与减排，具有一定的环保和经济效益。
