Applicability Analysis of Construction Waste Recycled Aggregate in Construction of Sponge City

Abstract

As the construction of sponge cities in China is in full swing, it is necessary to use a lot of crushed stones and gravels, which will damage the ecological environment. It is imminent to use recycled aggregates to replace natural crushed stones and gravels for sponge city construction. Aiming at the applicability of recycled aggregates in sponge cities, by conducting experimental research on the water absorption, water storage and water permeability characteristics of recycled aggregates, it is concluded that the water absorption and water storage properties of recycled aggregates are better than natural crushed stones and water permeability Slightly worse than natural crushed stone, further verifying the applicability of recycled aggregates in the construction of sponge cities, and the prospects for future popularization and application are considerable.
