Regenerative concrete composite material and method for making same

Abstract

The present invention discloses a regenerated concrete compound material, which is made of the following components according to weight ratio: 37-53 percent of regenerated aggregate prepared by the building waste residue, 14-30 percent of regenerated fine aggregate prepared by the building waste residue, 6-14 percent of industrial waste sand, 14-18 percent of common cement, 6-8 percent of water, additive and glue powder of waste tyre. The preparation method for the regenerated concrete is that: (1) the waste tyre is crushed and then is dipped in the coupling agent solution, and is to be dried; (2) the building waste residue is crushed, screened to obtain the regenerated coarse or fine aggregate; (3) the additive is added into the aggregate and the waste sand for mixing and blending evenly; (4) the regenerated aggregate, waste sand, cement, water and glue powder are milled evenly and then the regenerated concrete compound material can be obtained. The present invention can solve the problems that the building waste residue is difficult to be treated and the entironment is polluted and deteriorated greatly and so on. The building waste residue is to be used for replacing the natural aggregate that can decrease the consumptions to the natural aggregate in the building industry, solve the problems that the natural aggregates are increasingly lacked and the entironment is damaged by the exploitation of the sand stone. The present invention can protect the living environment for the human, guarantee the sustainable development for the society and accord to the requirement of the sustainable development.

Description

technical field [0001] The invention relates to a building material and a preparation method thereof, in particular to a recycled concrete composite material and a preparation method thereof. Background technique [0002] With the development of urban construction, a large amount of construction waste residues are produced, mainly waste concrete, waste bricks and tiles, waste mortar, waste stones, ceramic tiles, etc. These construction waste residues are difficult to deal with, resulting in the destruction and pollution of the ecological environment. The method of dealing with construction waste is mainly landfill, or as construction aggregate. Sand casting accounts for 80-90% of foundry production. The output of castings in my country is more than 10 million tons, and the amount of recycled sand is as high as 100 million tons. 10-20% of the recycled waste sand must be continuously discarded, and the discarded waste sand is 10 million tons. Scrap tires are difficult to deco...

Problems solved by technology

Waste tires are difficult to decompose and recycle as automobile waste. At present, they are mainly recycled in the way of refurbishment. Some parts that have no refurbishment value are incinerated, and some are used to make rubber powder.
