The invention discloses steel slag composite fiber pervious concrete, which is prepared from the following raw materials in parts by weight: 1200 to 1250 parts of coarse aggregate, 500 to 650 parts offine aggregate, 260 to 300 parts of ordinary Portland cement, 120 to 150 parts of water, 6 to 10 parts of a retarding and water reducing agent, 150 to 200 parts of silicon powder and 4 to 8 parts ofcomposite fiber, wherein the composite fiber is composed of natural fiber and modified polypropylene, and the length of the composite fiber is 7-9 mm. According to the steel slag composite fiber pervious concrete, steel slag is used as aggregate to improve the water permeability, composite fiber is added to improve the mechanical property of the concrete, and adopts the combination of natural fiber and modified polypropylene, wherein the shape of the natural fiber is utilized to improve the bond stress, and the alkali resistance of the modified polypropylene is utilized to improve the corrosion resistance of the natural fiber. By improving the components and the preparation process thereof, the comprehensive properties of water permeability, strength, impact resistance, durability and thelike of the concrete are greatly improved.
本发明公开了一种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，缓凝减水剂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。本发明的钢渣复合纤维透水混凝土通过钢渣来作为骨料，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。
