Steel slag pervious concrete and preparation process thereof
The invention relates to the technical field of novel building materials, in particular to steel slag pervious concrete and a preparation process thereof. On the first hand, the invention provides a cementing material for the steel slag pervious concrete, and the cementing material at least comprises the following components in parts by weight: 1-1.5 parts of Portland cement, 1-1.5 parts of mineral powder and 0.04-0.06 part of anhydrite fine powder. The invention provides steel slag pervious concrete on the second aspect, the steel slag pervious concrete is obtained by mixing and stirring thecementing material, a substrate material, water and a polycarboxylate superplasticizer, wherein the weight ratio of the cementing material to the substrate material to the water to the polycarboxylatesuperplasticizer is (3-4.6):20:(0.9-1.84):(0.045-0.0675). The base material comprises the following components in parts by weight: 5-7 parts of recycled aggregate, 27-28 parts of steel slag, 4-5 parts of steel slag aggregate and 3-5 parts of fine sand. The steel slag pervious concrete prepared by the method is high in compressive strength and low in cost.
本发明涉及新型建筑材料技术领域，特别是涉及一种钢渣透水混凝土及其制备工艺，本发明第一方面提供一种用于钢渣透水混凝土的胶凝材料，所述胶凝材料至少包括以下重量份的组分：硅酸盐水泥：1‑1.5，矿粉：1‑1.5，硬石膏磨细粉：0.04‑0.06。本发明第二方面提供一种钢渣透水混凝土，所述钢渣透水混凝土由第一方面所述胶凝材料、基底料、水和聚羧酸减水剂，混合搅拌获得，所述胶凝材料、所述基底料、所述水和所述聚羧酸减水剂的重量比为3‑4.6：20：0.9‑1.84：0.045‑0.0675，所述基底料包括以下重量份的组分：再生骨料：5‑7，钢渣：27‑28，钢渣集料：4‑5，细砂：3‑5。本发明制备的钢渣透水混凝土抗压强度高，成本低。
