High-strength pervious concrete and preparation method thereof
The invention discloses high-strength pervious concrete and a preparation method thereof. The preparation method comprises the following steps: (1) material preparation: preparing coarse aggregate, fine aggregate, a water reducing agent, a cementing material, hexagonal boron nitride, basalt fiber and water in parts by weight; (2) mixing: pre-mixing the coarse aggregate, the fine aggregate and 10% of water, adding the cementing material into the pre-mixed material after pre-mixing, and adding basalt fiber in the mixing process; then, stirring the remaining water, the water reducing agent and the hexagonal boron nitride; (3) molding in a mold; and (4) curing. The hexagonal boron nitride and the basalt fiber are added into the raw materials, and the hexagonal boron nitride has good lubricating property, so that the viscosity of the cementing material can be obviously increased, aggregate and the cementing material are tightly combined, and the compressive strength of the pervious concrete is improved; the basalt fiber is a novel high-performance fiber and can solve the problem of cracks caused by brittleness after being added into the pervious concrete, so that the compressive strength of the pervious concrete is enhanced.
本发明公开了一种高强度透水混凝土及其制备方法，（1）备料：按照重量份数准备粗骨料、细骨料、减水剂、胶凝材料、六方氮化硼、玄武岩纤维及水；（2）拌和：先将粗骨料、细骨料和10%的水进行预拌，预拌之后，再将胶凝材料加入预拌材料内，在搅拌过程中加入玄武岩纤维；随后，将剩下的水、减水剂以及六方氮化硼搅拌；（3）入模成型；（4）养护。本发明的原材料中添加六方氮化硼及玄武岩纤维，因六方氮化硼具有良好的润滑性能，能够明显增加胶凝材料的黏度，使骨料与胶凝材料紧密结合，从而提高透水混凝土的抗压强度；玄武岩纤维是一种新型高性能纤维，加入透水混凝土中，能解决由于脆性带来的裂缝问题，进而增强透水混凝土的抗压强度。
