Recycling construction waste can not only protect the environment, reduce its impact, choose scientific management and effective recycling measures, but also save a lot of construction funds and resources. Many waste materials in construction waste can be classified, removed, or crushed, and most of them can be reused as renewable resources. For example, construction waste is screened, crushed, and screened into thick aggregates to replace natural aggregates in the preparation of concrete, building bricks, and roadbed materials. This results in high recycling rates, low production costs, and a wide range of applications for construction waste, achieving material recycling.
Advocate energy conservation, consumption reduction, capacity reduction, and resource recycling. Taking the construction of green building recycling parks as the core concept and utilizing construction waste as a resource for comprehensive recycling and treatment.
The high-quality recycled aggregates produced can be used for building materials such as concrete, dry mixed mortar, wall materials, various blocks, bricks, etc. Meanwhile, plastic pipes, cables, and iron metals can be recycled, and wood can be recycled. Lightweight combustible materials are processed to produce derivative fuels, which utilize construction waste at a lower production cost, achieve higher benefits, realize sustainable development of the construction industry, and create considerable economic and social benefits.
Construction waste:
1. Waste wood - Unvisibly damaged wood can be directly used to rebuild buildings, while severely damaged wooden components can be used as raw materials for recycled wood boards or papermaking.
2. Abandoned pavement asphalt concrete - can be directly used as recycled asphalt mixture in moderate proportions.
3. Abandoned road concrete - can be processed into recycled aggregates for the preparation of recycled concrete.
4. Scrap steel bars, scrap iron wires, scrap electrical wires, and various scrap steel accessories can be sorted, centralized, and reheated to be processed and manufactured into various specifications of steel.
5. Waste materials such as abandoned building concrete, bricks, stone, etc. - can be used to produce concrete, mortar of corresponding strength grades, or to prepare building materials such as blocks, paving bricks, grid bricks, wall panels, floor tiles, etc.
6. Slag soil - can be used for road construction, pile foundation filling, foundation, etc.
Construction waste treatment equipment can conveniently and quickly achieve the crushing, screening, and impurity removal of construction waste. The screened construction waste is removed by specific iron removal equipment and processed into recycled sand and gravel aggregates with certain particle sizes through coarse, medium, and fine crushing equipment, which are used for road foundation stones, unburned bricks, cement admixtures, etc.
