Regenerated permeable concrete material prepared by using all components of construction waste and preparation method thereof

Abstract

The invention discloses a regenerated permeable concrete material prepared by using all components of construction waste and a preparation method thereof. The regenerated permeable concrete material is divided into a concrete base and a concrete facing. The method comprises the following steps: performing crushing and separation on construction waste to obtain construction waste coarse aggregate, construction waste fine powder and construction waste fine aggregate, preparing the concrete facing from the construction waste coarse aggregate and construction waste fine powder, and preparing the concrete base from the construction waste fine aggregate. The method can utilize all the components of the construction waste, and the utilization ratio is 100%. The prepared regenerated permeable concrete has the advantages of favorable permeation coefficient, favorable acoustical absorption coefficient and higher compression strength. The permeable system prepared from the regenerated permeable concrete material can satisfy the national standard on construction of sponge cities. The manufacturing cost is greatly lowered. The regenerated permeable concrete can be widely used in municipal construction.

[0002] In recent years, the problem of urban waterlogging has continued to emerge. At the same time, judging from the rainwater waterlogging incidents caused by Beijing, Guangzhou, Chengdu, Wuhan and other places in recent years, urban waterlogging has shown a strong upward trend. The Ministry of Housing and Urban-Rural Development conducted a survey on waterlogging in 351 cities in 32 provinces in 2010, showing that since 2008, 213 cities have experienced waterlogging to varying degrees, accounting for 62% of the surveyed cities; waterlogging disasters occur more than three times a year There are 137 cities in China, and it has even expanded to western and northern cities such as Xi'an and Shenyang, which are d...
