Composite fiber high-strength pervious concrete and preparation method thereof
The invention discloses composite fiber high-strength pervious concrete and a preparation method thereof, and relates to the technical field of concrete. The prepared composite fiber high-strength pervious concrete is prepared from cement, water, coarse aggregate, composite fibers, lime powder, silica fume and chloroprene rubber. The preparation method comprises the following steps: firstly, mixing polypropylene glycol propionate, aminated carbon fiber and porous steel slag for spinning to prepare composite fiber; cement, water, coarse aggregate, lime powder and silica fume are mixed, and cement slurry is prepared; and finally, mixing the cement slurry, the composite fibers and chloroprene rubber to prepare the composite fiber high-strength pervious concrete. The composite fiber high-strength pervious concrete prepared by the invention has good splitting tensile strength, compression resistance and anti-freezing performance.
本发明公开了一种复合纤维高强度透水混凝土及其制备方法，涉及混凝土技术领域。本发明制备的复合纤维高强度透水混凝土，包括水泥、水、粗骨料、复合纤维、石灰粉、硅灰、氯丁橡胶；本发明先将聚丙烯醇丙醛酸酯、氨基化碳纤维和多孔钢渣混合纺丝，制备得到复合纤维；再将水泥、水、粗骨料、石灰粉、硅灰混合，制备得到水泥浆料；最后，将水泥浆料、复合纤维、氯丁橡胶混合，制备得到复合纤维高强度透水混凝土；本发明制备得到的复合纤维高强度透水混凝土具备良好的劈裂抗拉强度、抗压性能、防冻性能。
