Pervious concrete as well as preparation method and application thereof
The invention provides pervious concrete which comprises recycled concrete superfine powder, recycled concrete particles, cement, natural medium sand, reinforcing fibers and water, and the specific surface area of the recycled concrete superfine powder ranges from 450 m < 2 >/kg to 700 m < 2 >/kg. The recycled concrete particles are continuous graded mixtures, the minimum particle size of the recycled concrete particles ranges from 1 mm to 10 mm, and the maximum particle size of the recycled concrete particles ranges from 15 mm to 30 mm; and the fineness modulus of the natural medium sand is 2.3 to 3.0. Through cooperative use of the raw materials with different particle sizes, the pervious concrete provided by the invention has strength and porosity meeting construction requirements.
本发明提供一种透水混凝土，包括：再生混凝土超微粉、再生混凝土颗粒、水泥、天然中砂、增强纤维和水，其中，所述再生混凝土超微粉的比表面积为450m/kg～700m/kg；所述再生混凝土颗粒为连续级配混合料，最小粒径为1mm～10mm，最大粒径为15mm～30mm；所述天然中砂的细度模数为2.3～3.0。通过不同粒径的原料的配合使用，使得本发明所提供的透水混凝土具有满足施工要求的强度和孔隙率。
