Besides a small part of waste sand is effectively utilized, a large amount of waste sand is discarded at will, which not only wastes resources, but also easily causes environmental pollution. In addition, during the casting process, the waste sand forms a relatively stable crystalline phase through high-temperature treatment, and shows the properties of wear resistance, high strength and the like in physical properties. At present, one feasible disposal method for the waste sand is to prepare the waste sand into baking-free water permeable bricks, such as: chinese patent "a whole sand-based water-permeable brick using foundry waste sand as aggregate and its manufacturing method (CN 107555838A)" and Chinese patent "production process for preparing composite sand-based water-permeable brick using foundry mould waste sand" (CN 107365106A) use cementing agent of cementing material such as epoxy resin and cement to prepare baking-free water-permeable brick. Although the baking-free water permeable brick is simple to prepare and low in cost, the baking-free water permeable brick has the common defects of low product strength, poor water permeability, easiness in pulverization, poor freeze-thaw resistance and short service life, and cannot exert the physical properties of the casting waste sand. With the advance of urbanization, materials with poor water permeability are generally adopted in the hardening process of urban roads, and the utilization of the materials does not help to solve urban waterlogging and relieve urban heat island effect for building 'ecological sponge cities'.
