Modified fiber type composite high-pervious concrete and preparation method thereof
The invention discloses modified fiber composite high-pervious concrete and a preparation method thereof, and belongs to the technical field of concrete. The modified fiber composite high-pervious concrete is prepared from the following components: Portland cement, fly ash, coarse aggregate, composite fibers, waterborne polyurethane emulsion, activated charcoal, a water reducing agent, compound bacteria liquid, a photocatalyst and water. The modified polypropylene fiber, the modified carbon fiber, the waterborne polyurethane emulsion and the activated charcoal are added into the concrete raw materials, so that the mechanical property of the concrete can be enhanced, the stability, the compressive strength and the crack resistance of the concrete can be improved, the hole structure of the concrete can be increased, and the water permeability of the concrete is further improved; meanwhile, by adding the microbial liquid and the photocatalyst, the self-repairing and self-cleaning capabilities of the concrete are improved.
本发明公开了混凝土技术领域的一种改性纤维复合高透水混凝土及其制备方法，包括如下组分：硅酸盐水泥、粉煤灰、粗骨料、复合纤维、水性聚氨酯乳液、活化生物炭、减水剂、复合菌液、光催化剂和水。本发明通过向混凝土原料中添加改性聚丙烯纤维、改性碳纤维、水性聚氨酯乳液和活化生物炭，既能加强混凝土的力学性能，提高其稳定性、抗压强度和抗裂性，又能增加混凝土的空穴结构，进一步提高混凝土的透水性；同时通过添加微生物菌液和光催化剂，提高混凝土自修复和自清洁能力。
