Permeable compressive concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses water-permeable compressive concrete and a preparation method thereof.The water-permeable compressive concrete is prepared from, by weight, 150-200 parts of cement, 1000-1500 parts of gravel, 150-200 parts of fine sand, 20-30 parts of a composite reinforcing agent, 3-4 parts of a water reducing agent and 150-180 parts of water; the composite reinforcing agent is prepared from the following raw materials in parts by weight: 100 to 200 parts of redispersible polymer latex powder and 50 to 100 parts of modified glass fiber; the modified glass fibers are obtained by coating and modifying glass fibers through multi-walled carbon nanotubes. The 28d compressive strength of the concrete obtained in the invention is 46.1-65.2 MPa, and the compressive strength of the pervious concrete is improved under the condition of ensuring the water permeability.
本申请涉及混凝土技术领域，具体公开了一种透水抗压混凝土及其制备方法，一种透水抗压混凝土，其包括如下重量份的原料：水泥150‑200份、碎石1000‑1500份、细砂150‑200份、复合增强剂20‑30份、减水剂3‑4份、水150‑180份；所述复合增强剂包括如下重量份的原料：可再分散聚合物乳胶粉100‑200份、改性玻璃纤维50‑100份；所述改性玻璃纤维为玻璃纤维通过多壁碳纳米管包覆改性而得。本申请得到的混凝土28d抗压强度为46.1‑65.2MPa，在保证透水性能的情况下，提高了透水混凝土的抗压强度。
