High polymer environment-friendly recycled concrete and preparation method thereof

The invention discloses high polymer environment-friendly recycled concrete and a preparation method thereof, and relates to the technical field of concrete. The problem that cracks exist in recycled concrete, and consequently the mechanical strength is poor is solved. The recycled concrete comprises the following components in parts by weight: 200-250 parts of a framework material, 20-40 parts of a gelling filling material, 4-6 parts of a functional additive and 10-30 parts of water, the framework material comprises regenerated aggregate, fly ash, slag powder, gravel or river sand in a mass ratio of 10: 2: 1: 15. The preparation method of the recycled concrete comprises the following steps: removing garbage, retaining waste concrete blocks, crushing the waste concrete blocks, and screening aggregate as recycled aggregate; the method comprises the following steps: sequentially adding the waste coarse aggregate and the filling material into an accommodating tank, uniformly mixing and oscillating, adding the wa
