High-pervious concrete admixture and pervious concrete
The invention relates to the technical field of building materials, and discloses a high-pervious concrete admixture and pervious concrete. The pervious concrete admixture is prepared from the following raw materials in parts by weight: 25 to 35 parts of acrylic resin, 5 to 10 parts of modified polypropylene fiber, 15 to 25 parts of water reducing agent, 7 to 10 parts of kaolin and 15 to 25 parts of reinforcing filler, acrylic resin is used as an adhesive structure, and a functional additive is added to improve the compression resistance, the impermeability and the water permeability of the pervious concrete; wherein due to the introduction of the reinforcing filler, the compressive strength and the impermeability of the matrix are improved, and the water permeability, the pressure resistance and the impermeability of the matrix can be improved through the synergistic effect of the modified polypropylene fibers and the reinforcing filler, so that the service life of the pervious concrete is prolonged.
本发明涉及建筑材料技术领域，公开了一种高透水混凝土外加剂及透水混凝土。本发明的透水混凝土外加剂，包括以下重量份的原料：丙烯酸树脂25‑35份，改性聚丙烯纤维5‑10份，减水剂15‑25份，高岭土7‑10份，增强填料15‑25份；它以丙烯酸树脂为胶黏结构，并添加功能助剂提高透水混凝土的抗压性能、抗渗性能以及透水性能；其中，增强填料的引入提高了基体的抗压强度和抗渗性能，而改性聚丙烯纤维能与增强填料协同作用提高基体的透水性、抗压性以及抗渗性，进而提高透水混凝土的使用寿命。
