High-permeability pervious concrete cementing agent and preparation method and application thereof

The invention relates to a high-permeability pervious concrete cementing agent which is characterized by comprising the following components in parts by weight: 2-3 parts of furfural acetone resin, 100 parts of cement, 4-6 parts of epoxy resin, 1-2 parts of solidifying agent and 2-4 parts of toughening agent, wherein the cement is 42.5-grade ordinary portland cement; the furfural acetone resin comprises furfural and acetone; the epoxy resin is commercially available E-44; the toughening agent is polyurethane synthesized by utilizing water-soluble toluene 2,4-diisocyanate and trimethylolpropane; the solidifying agent is mixed polyamine of m-xylylenediamine and epoxy chloropropane at a ratio of 1:1. The invention also relates to a preparation method of the high-permeability pervious concrete cementing agent and application of the high-permeability pervious concrete cementing agent in a pervious concrete product. The high-permeability pervious concrete cementing agent disclosed by the invention has the advantage
