Construction waste recycling technology

Abstract

The invention discloses a construction waste recycling technology comprising the following treatment steps: S1, classifying construction wastes, clearing and screening relatively complete bricks and tiles which can be reused after being cleaned; S2, fully crushing waste bricks, tiles and concrete screened out, using crushed powder to prepare low-grade recycled aggregate concrete for foundation reinforcement, road engineering bedding, indoor floor and floor bedding, and production of non-load-bearing concrete hollow blocks, concrete hollow partition panels and autoclaved fly ash bricks; S3, enabling waste wood screened out in a construction project to pass a wood crushing machine; S4, conveying waste metal and steel materials screened out to a steel plant or a nonferrous metal smelter for remelting; and conveying waste glass screened out to a glass factory or a glass-ceramic factory as production raw materials. According to the construction waste recycling technology, urban traffic pressure and environmental pollution caused by transportation can be relieved, and the construction waste recycling technology benefits protection of cultivated land and ecological environment, and is ofenvironmental significance.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a construction waste recycling process. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste bricks and other wastes generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. According to the source of generation, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; according to the composition, construction waste can be divided into muck, concrete blocks, broken stones, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. Construction waste refers to the construction waste produced by man-made or natural reasons in the project, including waste residue, spoil, silt and waste materials, etc. These materials are of no h...

Problems solved by technology

The vast majority of construction waste is transported to the suburbs or villages without any treatment, and is stacked or buried in the open air, which consumes a lot of construction funds such as land acquisition fees and garbage removal; It can cause serious environmental pollution. From the composition characteristics of construction waste, it can be seen that a large part of it can be recycled. To solve these problems, traditional formulas and processes need to be improved. Therefore, here we propose construction waste recycling. use of technology
