Pervious concrete structure and preparation process thereof
The invention discloses a pervious concrete structure and a preparation process thereof. The invention discloses a pervious concrete structure which comprises a foundation structure, a first perviousconcrete structure and a second pervious concrete structure, and a double-acrylic polyurethane sealing layer is arranged above the second pervious concrete structure; the first pervious concrete structure is composed of first cement, coarse aggregate, first mixing water, a first reinforcing material and a first water reducing agent. The composition ratio of the components is 375: 1540: 112: 7.3: 0.55, wherein the particle size of the coarse aggregate is 5-15 mm, the second pervious concrete structure is composed of second cement, fine aggregate, second mixing water, a second reinforcing material, a second water reducing agent and an inorganic pigment according to the composition ratio of 375: 1540: 112: 7.3: 0.55: 0.75, and the particle size of the fine aggregate is 3-4 mm; wherein the initial setting time of the first cement and the second cement is not less than 45 minutes, and the final setting time is not more than 6.5 hours; by means of the mode, construction is easy and convenient, the construction cost is low, the water permeability is excellent, and the abrasion resistance and the strength performance are good.
一种透水混凝土结构及其制备工艺。本发明公开了一种透水混凝土结构，包括地基结构、第一透水混凝土结构和第二透水混凝土结构，所述第二透水混凝土结构的上方设置有双丙聚氨酯密封层；所述第一透水混凝土结构由第一水泥、粗骨料、第一拌合用水、第一增强料和第一减水剂组成，其组成配比为375：1540：112：7.3：0.55，所述粗骨料的粒径为5～15mm，所述第二透水混凝土结构由第二水泥、细骨料、第二拌合用水、第二增强料、第二减水剂和无机颜料组成，其组成配比为375：1540：112：7.3：0.55：0.75，所述细骨料的粒径为3～4mm；所述第一水泥和所述第二水泥的的初凝时间不得少于45min，终凝时间不得大于6.5h；通过上述方式，本发明能够不仅施工简单方便，施工成本低，而且透水性优异，耐磨性能和强度性能好。
