Pervious concrete with runoff purification effect and preparation method thereof
The invention provides pervious concrete with a runoff purification effect. The pervious concrete is prepared from the following raw materials in parts by weight: 58-60 parts of aggregate, 30-32 parts of cement, 9-10 parts of water and 0.18-0.2 part of a water reducing agent. A stone wrapping method is used as a stirring method, and vibration pressing forming is used as a forming method, so that the strength grade of the pervious concrete reaches C30, namely the compressive strength is greater than or equal to 30MPa, the breaking strength is greater than or equal to 5MPa, and the permeability coefficient is greater than or equal to 2mm/s. The performance meets the national standard requirements, and meanwhile, the effect of purifying part of pollutants is achieved.
本发明提供一种具有径流净化效果的透水混凝土，由下列原料按照如下的重量配比制成：骨料58‑60份、水泥30‑32份、水9‑10份、减水剂0.18‑0.2份。本发明选用裹石法作为搅拌方法、振压成型作为成型方法，使得透水混凝土的强度等级达到C30，即抗压强度大于或等于30MPa、抗折强度大于或等于5MPa，同时透水系数大于或等于2mm/s。在性能达到国家标准要求的同时，还具有净化部分污染物的作用。
