Premixed pervious concrete with high strength and preparation method thereof
The invention discloses premixed pervious concrete with high strength and a preparation method thereof, and particularly relates to the technical field of concrete preparation, and the premixed pervious concrete comprises the following components in parts by weight: 300-500 parts of cement, 1200-1600 parts of gravel, 100-160 parts of water, 5-15 parts of a reinforcing agent, 5-12 parts of a premixing agent, 100-300 parts of machine-made sand, 5-10 parts of a water repellent and 10-30 parts of carborundum. The ready-mixed concrete designed by the invention can adjust the water permeability as required during use, so that the effect of adjusting the service life is achieved, the compressive strength and breaking strength are relatively high during use as a whole, the structural strength and wear resistance of the prepared concrete are further improved by utilizing the added carborundum structure, and the ready-mixed concrete is high in heat conductivity coefficient, small in thermal expansion coefficient and high in water permeability. And pavement paving is utilized.
本发明公开了一种具备高强度的预拌透水混凝土及其制备方法，具体涉及混凝土制备技术领域，包括以下成分及其重量份：水泥300‑500份、碎石1200‑1600份、水100‑160份、增强剂5‑15份、预拌剂5‑12份、机制砂100‑300份、憎水剂5‑10份、金刚砂10‑30份。本发明设计的预拌混凝土能够在使用时根据需要调节透水性能，进而达到调节使用寿命的效果，且整体上在使用时抗压、抗折强度较高，利用加入的金刚砂结构进一步提高制备后的混凝土结构强度和耐磨性能，且导热系数高、热膨胀系数小，利用路面的铺设使用。
