Pervious concrete as well as preparation method and application thereof
The invention relates to the technical field of concrete, and discloses pervious concrete as well as a preparation method and application thereof. The pervious concrete is prepared from the following raw materials: cement, fly ash, fine aggregate, coarse aggregate, a water reducing agent, carbon nanotube modified carbon fibers, hydrophobic modified hydroxyethyl cellulose and water, wherein the particle size of the fine aggregate is 3.5 to 4.75 mm, the particle size of the coarse aggregate is 4.76 to 9.5 mm, and the water cement ratio of the pervious concrete is 0.2 to 0.25. According to the invention, by designing the continuous size fraction aggregate and then matching the continuous size fraction aggregate with the carbon nanotube modified carbon fiber and the hydrophobic modified hydroxyethyl cellulose, the prepared pervious concrete not only has excellent compressive strength (greater than 60 MPa) and permeation coefficient (greater than 4 mm/S), but also has excellent anti-clogging performance, and when the pervious concrete is applied to pavement construction, not only can the pavement repairing cost be reduced, but also the service life of the pavement is prolonged. And rapid development of urban pavement construction can be promoted.
本发明涉及混凝土技术领域，公开了一种透水混凝土及其制备方法和应用。本发明的透水混凝土制备原料包括：水泥、粉煤灰、细骨料、粗骨料、减水剂、碳纳米管改性碳纤维、疏水改性羟乙基纤维素和水；其中，所述细骨料的粒径为3.5～4.75mm，所述粗骨料的粒径为4.76～9.5mm，所述透水混凝土的水灰比为0.2～0.25。本发明通过设计连续粒级骨料，然后搭配碳纳米管改性碳纤维和疏水改性羟乙基纤维素，制得的透水混凝土不仅具有优异的抗压强度(大于60MPa)和透水系数(大于4mm/S)，而且具备优异的抗堵塞性能，将其应用于路面建设，不仅能够降低路面修缮成本，而且有助于促进城市路面建设的快速发展。
