The invention discloses steel slag composite fiber pervious concrete containing hydrolyzed organic matters. The pervious concrete is prepared from, by weight, 1200-1250 parts of coarse aggregate, 500-650 parts of fine aggregate, 260-300 parts of ordinary Portland cement, 120-150 parts of water, 6-10 parts of hydrolyzed polyacrylamide, 150-200 parts of silicon powder and 4-8 parts of composite fibers, wherein the composite fibers are composed of natural fibers and modified polypropylene, and the length of the composite fibers is 7-9 mm. According to the steel slag composite fiber pervious concrete containing hydrolyzed organic matters, the porous basalt and the steel slag are used as aggregates to improve the water permeability, and the composite fibers are added to improve the mechanical property of the concrete. The composite fibers adopt the combination of the natural fibers and the modified polypropylene, the shape of the natural fibers are utilized to improve the bond stress, and the alkali resistance of the modified polypropylene is utilized to improve the corrosion resistance of the natural fibers. By improving the components and the preparation process thereof, the comprehensive properties of the concrete including water permeability, strength, impact resistance and durability are greatly improved.
本发明公开了一种含水解有机物的钢渣复合纤维透水混凝土，其原料包括以下重量份的组份：粗骨料1200～1250份，细骨料500～650份，普通硅酸盐水泥260～300份，水120～150份，水解聚丙烯酰胺6～10份，硅粉150～200份，复合纤维4～8份；其中，所述复合纤维由天然纤维和改性聚丙烯组成，所述复合纤维的长度为7～9mm。本发明的含水解有机物的钢渣复合纤维透水混凝土通过多孔玄武岩和钢渣来作为骨料，以提高透水性，并加入复合纤维以提高混凝土的力学性能。该复合纤维采用天然纤维和改性聚丙烯的组合，利用天然纤维的形状来提高握裹力，利用改性聚丙烯的抗碱性来提高天然纤维的耐腐蚀性。本发明通过组份及其制备工艺的改进，大大提高了混凝土的透水性、强度、抗冲击、耐久性等综合性能。
