The recycling of construction waste is a process to turn construction waste into treasure. For example, besides landfill of construction waste, in developed countries, construction waste is used as raw material to make recycled aggregate for concrete and brick making. Some researchers pointed out that the construction waste body is a treasure, after the effective development, China's construction waste utilization rate can reach more than 95%.
1. Classification and treatment of construction waste: it is mainly used to sort and recycle the rebar, metal and wood that can be reused in construction waste.
2. construction waste into renewable brick: solid clay brick as a traditional building materials is no longer adapt to the needs of times development, use new building materials, such as the construction waste recycled brick production can not only meet the market demand for building materials is environmental protection, can also consume a large amount of construction waste, such as the production of 150 million pieces of standard brick can consume more than 40, ten thousand tons of construction waste, save the heap garbage covers an area of 160 mu.
3. Construction waste production of recycled aggregate: the utilization of construction waste production of recycled aggregate is also one of the main ways of recycling construction waste in China. Will construction waste after preliminary cleaning, sorting out the recycled steel and wood, then put the bricks, cement concrete block after break into aggregate crushing equipment, through the sieve sieve grading, removing impurities, forming a certain particle size of raw material requirements of building materials, and then according to the gradation design requirement in raw materials adding auxiliary materials such as cement and fly ash, join part of soil water after mixing into concrete, used to make different building and road construction products, these products can completely replace the normal application used for roads and other infrastructure.
