All kinds of wastes are produced in all walks of life, especially the construction industry produces a lot of various kinds of construction wastes every year. According to statistics from relevant departments, China's existing building area totals more than 40 billion square meters. Based on the standard of 500t to 600t of construction waste generated per 10,000 square meters of building construction, China's existing building area has generated at least 2 billion tons of construction waste. By 2020, China will also add about 30 billion square meters of construction area, and the newly generated construction waste will be an astronomical figure. In most places, construction waste is disposed of in landfills or stacked in the open air. If landfilling or open storage is not a long-term solution, it will not only pollute the environment, but also a waste of resources. Here are some examples of construction waste disposal methods: Reuse of old wood and sawdust: Old wood removed from buildings can be reused directly as wood. Broken wood, sawdust and sawdust from construction waste can be used as a cover in fuel composting and erosion projects. Compared with ordinary concrete, waste wood is used to produce clay, wood, cement composite materials, which has the advantages of light weight and low heat conductivity. Can be used as a special insulation material. Reuse of old bricks and tiles: Bricks and tiles in construction waste can be cleaned and reused. Waste bricks, tiles and concrete are crushed and screened by Construction Waste crusher equipment. After cleaning, they can be used as recycled aggregates to prepare low-standard recycled aggregate concrete. Manufactured in road engineering cushions, indoor floors and floor cushions, non-load-bearing concrete hollow blocks, concrete hollow partition boards, autoclaved fly ash bricks, etc. The recycled aggregate component contains a considerable amount of cement mortar, which results in high recycled porosity and large water absorption. Recycling of scrap metal and steel: Construction waste treatment equipment is equipped with iron removers to sort scrap metal and steel. The sorted scrap metal and steel can be sent to iron and steel plants or non-ferrous metal smelters for refining; Recycling of waste linoleum: After being crushed, sieved, and cleaned by construction waste treatment equipment, it is used as concrete aggregate or sintered brick. Reuse of old asphalt pavement: The old asphalt pavement is crushed and screened by Construction Waste crusher equipment, mixed with recycled materials, new aggregates, and new asphalt materials in appropriate proportions to form a certain pavement of recycled asphalt concrete for paving the road The surface layer or base layer, the asphalt roofing material contains high-quality fillers, which can replace part of the cold-mixed and hot-mixed asphalt. The asphalt layer material also has a fibrous structure, which helps improve the performance of the hot-mixed asphalt. Concrete accounts for about 30% of the total construction waste, which is an important component and the part with the highest recycling value. After being broken by construction waste treatment equipment, concrete can be used for recycled concrete and recycled cement. As a roadbed material.
