Embodiment Construction

[0018] Some, but not all, embodiments of the present invention will be combined below. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see figure 1 , in an embodiment of the present invention, a construction waste recovery process, including aggregate production process, ready-mixed mortar production process, block production process and wall panel production process, the specific steps of the process are as follows: (1) Solid waste building Garbage is classified, and non-metallic and wood waste packaging materials are directly used as other industrial raw materials. Other solid waste construction waste, including muck, concrete blocks, crushed stones, brick and tile fragments, waste mortar, mud and asphalt blocks, are all transported to the raw material warehouse; (2) The construction waste construction re...

Abstract

The invention discloses a construction waste recycling technology. The technology comprises an aggregate production technology, a premixed mortar production technology, a building block production technology, and a wallboard production technology. The construction wastes are graded, grinded, and sieved to produce aggregate that can replace the natural sand and stones. Part of the aggregate can be used to produce premixed mortar, cement mixed material, and concrete products. The residual aggregate is packed as commercial aggregate for sale, and can be used in concrete mixing plants, premixed mortar plants, and road structural foundation backfilling. The produced powder can be used to product concrete products, and the produced soil can be directly used as greening soil. The construction wastes are graded, removed, or grinded, and then subjected to a series of technological procedures, so that the wastes are converted into renewable resources and reutilized, and the economic profit is prominent. The sprayed dusts and sands which cause severe environmental pollution during the transportation and storage process are avoided. Solved is the problem that plants cannot grow on the soil that is used to bury construction wastes.

Description

technical field [0001] The invention relates to the field of waste recycling, in particular to a construction waste recycling process. Background technique [0002] Construction waste, also known as construction waste, refers to the residual mud, slag, mud and other waste generated during the construction, demolition, repair of various buildings and structures by construction units or individuals, and the process of residents' house decoration. . According to the source classification, construction waste can be divided into five categories: land excavation, road excavation, old building demolition, building construction, and building material production, mainly consisting of muck, crushed stones, waste mortar, brick fragments, and concrete blocks. , asphalt blocks, waste plastics, waste metal materials, waste bamboo and wood, etc. The composition of construction waste produced by buildings of different structures is different, and its basic composition is consistent, mainl...
