| titleOfInvention | Pervious concrete and preparation method thereof |
| abstract | The invention discloses pervious concrete and a preparation method thereof, relating to the technical field of concrete material preparation; the pervious concrete is prepared with the concrete material including coarse aggregate 1000-1100 weight portions, cement 180-260 weight portions, water 60-90 weight portions, zeolite powder 20-40 weight portions and water reducing agent 6-9 weight portions; the concrete raw material also comprises an additive, and the additive is mainly prepared from the following raw materials in parts by weight: 3-7 parts of acetylated distarch phosphate, 2-5 parts of hydroxyethyl sodium sulfonate and 4-8 parts of polyvinyl alcohol fiber. The pervious concrete has the advantage of good water permeability. The preparation method of the pervious concrete comprises the following steps: preparing an additive, mixing materials, preparing pervious concrete and the like. The preparation method of the pervious concrete has the advantage of improving the water permeability of the product conveniently. |
