Performance Simulation of Permeable Concrete Materials Combined with Nanotechnology in Rainwater Management

In recent years, China has entered a period of rapid urban development, but most the cities with development still have ground hardening, which makes it difficult for rainwater to penetrate and discharge. order achieve drainage accumulated water in city, nanotechnology was introduced, permeable concrete based on NC NS nanomaterials proposed. Combined finite element analysis, properties mechanical mixed were analyzed. A comprehensive performance analysis pervious shows that viscosity is significantly higher than non-mixed concrete, permeability coefficient can reach 0.43 cm/s. incorporation improve compressive strength concrete. At same time, under environment simulation, retention time only 2.35 s. The above results show into increase its service life, great significance management.
