The present invention discloses a water-permeable concrete produced by using
solid-state waste, and a preparation method thereof, wherein the water-permeable concrete comprises, by weight, 11.0-22.0 parts of
cement, 6.0-11.0 parts of an active micro-
powder admixture, 74.0-80.0 parts of a recycled aggregate, 0.3-0.6 part of a polycarboxylic
acid water-
reducing agent, 0.3-1.0 part of an interfacial binder, and 3.0-8.0 parts of water. According to the present invention, the strength and the water permeability of the concrete are improved, and the reasonable re-use of the waste is achieved; the preparation method comprises: mixing the recycled aggregate, the interfacial binder and 50% of water, carrying out first stirring, adding the active micro-
powder admixture and the
cement, carrying out second stirring for 15 s, adding the polycarboxylic
acid water-
reducing agent, carrying out third stirring, finally adding 50% of the water, and carrying out fourth stirring for 1-3 min; and the
slurry easily wrap the aggregates, the adhesion is proper, the workability is easy to ensure, and the strength is high after hardening.
