Fiber-reinforced recycled aggregate pervious concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to fiber-reinforced recycled aggregate pervious concrete and a preparation method thereof. The fiber reinforced recycled aggregate pervious concrete is prepared from the following raw materials in parts by weight: 280 to 320 parts of cement, 90 to 110 parts of fly ash, 90 to 110 parts of mineral powder, 1100 to 1300 parts of aggregate, 18 to 22 parts of reinforcing agent, 3.5 to 5 parts of water reducing agent, 1.5 to 2.5 parts of fiber composition, 50 to 70 parts of hydrophobic modified inorganic filler and 105 to 115 parts of water, the aggregate comprises a primary aggregate and a recycled aggregate, and the weight part ratio of the primary aggregate to the recycled aggregate is (6-8): 3; the hydrophobic modified inorganic filler is prepared by carrying out surface treatment on an inorganic filler through a silane coupling agent and then loading fluorinated silicone rubber on the surface; the method has the advantage of improving the compressive strength of the pervious concrete.
本申请涉及混凝土的技术领域，尤其是涉及一种纤维增强再生骨料透水混凝土及其制备方法，所述纤维增强再生骨料透水混凝土包括如下重量份的原料：水泥280‑320份、粉煤灰90‑110份、矿粉90‑110份、骨料1100‑1300份、增强剂18‑22份、减水剂3.5‑5份、纤维组合物1.5‑2.5份、疏水改性无机填料50‑70和水105‑115份；所述骨料包括原生骨料和再生骨料，原生骨料和再生骨料的重量份比为（6‑8）：3；所述疏水改性无机填料通过无机填料经硅烷偶联剂进行表面处理，然后表面负载氟硅橡胶制得；其具有提高透水混凝土的抗压强度的优点。
