With the rapid urbanization of China, plenty of construction waste generated. The constituents of construction waste are bricks, concrete, rocks, scrap wire and steel, which can be recycled after processing. Therefore, dealing with the problem in a reasonable way has become the major issue in society.
Construction waste recycling is a systematic project, and we should attach great importance to improve the technical level of construction waste disposal. Most of the construction waste can be reused as renewable resources, for example, abandoned concrete and bricks can be crushed by the mobile crushing station, and the coarse-crushed aggregates can be used for the production of corresponding concrete, blocks, panels, tiles and other building materials. The coarse aggregates can also be used for road pavement base after adding solid materials. Brick is the burned clay material, which has activity of volcanic power after grinding, and it can be used as concrete admixtures to substitute fly ash, slag powder and so on. In recent years, mobile crushing station, which is economical and environmentally friendly, is tailored for the construction waste disposal, and it can change construction waste into building materials through crushing and sand making processes.
China started late in construction waste disposal, which is an imminent problem now. Because of urbanization and the demolition of cities, a large number of construction solid wastes appear every day. As for the pile and landfill of the waste, it not only occupies the land, but also brings serious groundwater and air pollution resulted from the fermentation and flushing of temperature and water.
