Construction waste refers to the residue, waste, waste material, residual mud and other wastes produced in the course of construction, construction units or individuals'construction, laying or dismantling of various buildings, structures, pipe networks, etc. According to the source classification, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc. According to the composition classification, construction waste can be divided into dregs and soil, concrete blocks, broken stones, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. These materials for the building itself is not helpful, but is generated in the process of building materials, need to be dealt with accordingly, so as to achieve the desired project construction.

Construction waste Processing technology

Large-scale construction waste crusher can meet the needs of construction waste crushing, the equipment is mainly for bulk materials, and high production, simple operation, easy maintenance. At present, the crusher suitable for construction waste treatment on the market is a kind of equipment called crushing and screening combined integration - fixed crushing and screening station, tire mobile crushing and screening station, etc. Vanguard's construction waste moving and crushing station adopts advanced construction waste treatment technology. By treating construction waste, industrial waste, coal cinder, coal rock, slag, fly ash, non-metallic solid waste of building materials and other waste materials, various types of new construction materials conforming to the quality inspection standards can be produced after solid waste treatment. According to the equipment configuration, the effective utilization rate of construction waste can reach 80-100%, without secondary pollution, and can achieve the ideal environmental protection effect of near zero pollution and zero discharge. Vanguard's mobile construction waste crushing plant integrates construction waste materials, crushing, transmission, treatment, reprocessing and other process equipment into one, through the combination of different equipment into a powerful mobile production line, to complete a multi-demand construction waste processing operations. The workstation has the characteristics of structure optimization, lightness and rationality, multi-function and so on, which overcomes the disadvantages of large space occupied by the separate placement of equipment components and complicated operation. The new building materials industry chain and the circular economy and low carbon economy production and operation mode will be changed from the traditional "building material building building waste" to "building material building building waste renewable materials new products".
With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly. The accompanying construction waste is increasing day by day. The amount of construction waste in China has accounted for more than one third of the total urban waste. China is in a period of rapid economic development, and hundreds of millions of tons of construction waste are unavoidable annually. If it is not handled and utilized in time, it will bring adverse effects to society, environment and resources. The coarse and fine aggregates produced from abandoned building concrete and masonry can be used to produce concrete, mortar or building materials such as blocks, wallboards, floor tiles. Coarse and fine aggregate can also be used for road surface base after adding curing materials. The waste brick and tile can be used to produce recycled aggregate bricks, blocks, wall panels, floor tiles and other building materials. Muck can be used for road construction, pile foundation, foundation and so on. Waste road concrete can be processed into recycled aggregate for the preparation of recycled concrete.

Application fields Through the deep processing, Construction waste can be widely used in the following industries.
