High-wear-resistance lightweight pervious concrete and preparation method thereof
The invention discloses high-wear-resistance lightweight pervious concrete. The high-wear-resistance lightweight pervious concrete is prepared from the following components: 15 to 30 percent of cement, 15 to 35 percent of admixture, 30 to 60 percent of aggregate and 7 to 12 percent of water, wherein the sum of the cement and the admixture is called a gel material. The high-wear-resistance lightweight pervious concrete further comprises fibers, a water reducing agent, a foaming agent and a foam stabilizer. The weight of the fiber is 0.5-3% of the weight of the gel material, the weight of the foaming agent is 0.02-0.5% of the weight of the gel material, the weight of the foam stabilizer is 0.02-0.35% of the weight of the gel material, and the weight of the water reducing agent is 0.03-2% of the weight of the gel material. The high-wear-resistance lightweight pervious concrete has a three-dimensional pore structure supported by a large amount of sand aggregate, and the addition of the large amount of sand aggregate ensures that the surface of the concrete has an enough skeleton effect to form a high-wear-resistance characteristic; the pores enhance the water permeability and the water storage property, so that dirt in water is favorably filtered, and a purification effect is achieved; the porosity of the high-wear-resistance lightweight pervious concrete is 40-85%; the density is low, the density is only 300-1300 kg/m < 3 >, the construction cost is reduced, and good compressive strength and breaking strength are achieved.
本发明公开了一种高耐磨轻质透水混凝土。高耐磨轻质透水混凝土由以下组分组成：水泥15‑30％、掺和料15‑35％、骨料30‑60％，水7‑12％。其中，水泥和掺和料的总和称为凝胶材料。高耐磨轻质透水混凝土还包括纤维、减水剂、发泡剂和稳泡剂。纤维为凝胶材料重量的0.5‑3％，发泡剂为凝胶材料重量的0.02‑0.5％,稳泡剂为凝胶材料重量的0.02‑0.35％，减水剂为凝胶材料重量的0.03‑2％。高耐磨轻质透水混凝土具备以大量砂骨料支撑的三维孔隙结构，大量砂骨料的加入，确保其表面有足够的骨架效应，形成高耐磨特性；其孔隙增强了其透水性，蓄水性，有利于对水中的污物进行过滤，起到了净化作用；高耐磨轻质透水混凝土孔隙率为40‑85％；密度轻，密度仅为300‑1300kg/m3,降低工程造价成本的同时具有良好的抗压强度和抗折强度。
