Pervious concrete reinforcing agent as well as preparation method and application thereof

The invention relates to the technical field of pervious concrete, in particular to a pervious concrete reinforcing agent as well as a preparation method and application thereof. The pervious concrete reinforcing agent comprises the following components: a first component: one or two of silica fume and phosphorus slag powder; the second component is one or more of sodium sulfate, sodium lignin sulfonate, hydroxypropyl methyl cellulose and wood fiber. According to the invention, solid waste silica fume or phosphorus slag powder is taken as a main base material for compounding the reinforcing agent, and solid waste resources are recycled, so that the environmental pollution is reduced, and the production cost is also greatly reduced; in addition, the high-titanium blast furnace slag pervious concrete prepared by adopting the pervious concrete reinforcing agent disclosed by the invention is high in strength and good in water permeability. 本发明涉及透水混凝土技术领域，尤其是涉及一种透水混凝土增强剂及其制备方法和应用。该透水混凝土增强剂包括以下组分：第一组分：硅灰、磷渣粉中的一种或两种
