Pervious concrete and preparation method thereof
The invention relates to the technical field of concrete materials, in particular to pervious concrete and a preparation method thereof. The pervious concrete is prepared from components in parts by weight as follows: 90-110 parts of Portland cement, 40-55 parts of water, 300-340 parts of coarse aggregate, 14-18 parts of diatomite powder, 3-4 parts of polypropylene fibers, 12-15 parts of an additive, 2-4 parts of a composite water reducing agent and 0.8-1.5 parts of an acrylamide-acrylic acid copolymer. The prepared pervious concrete forms a honeycomb structure with uniform pores, has good water permeability, compressive strength and durability, can filter and adsorb harmful substances in runoff water, and has good economic benefits and social benefits, the preparation method is simple andefficient, the operation process is convenient and easy to control, industrial production is facilitated, and the prepared product is stable in quality.
本发明涉及混凝土材料技术领域，具体涉及一种透水混凝土及其制备方法。所述透水混凝土包括以下重量份的组分：硅酸盐水泥90‑110份、水40‑55份、粗骨料300‑340份、硅藻土粉14‑18份、聚丙烯纤维3‑4份、外加剂12‑15份、复合减水剂2‑4份、丙烯酰胺‑丙烯酸共聚物0.8‑1.5份。制得的透水混凝土形成孔隙均匀的蜂窝状结构，具有良好的透水性、抗压强度和耐久性，并可过滤和吸附径流水中的有害物质，具有良好的经济效益和社会效益，其制备方法简单高效，操作过程方便易控，便于工业化生产，制备的产品质量稳定。
