Study on Recycling Method of Waste Concrete Economic Pengfei Li 1, a, Tao Guo 1,b Ligang Zhang1,c and Tengfei He 1,d 1 Department of Civil Engineering，Hebei Institute of Architecture and Civil Engineering, Zhangjiakou，Hebei，075000，China a365219355@qq.com, b67741234@qq.com, c313694437@qq.com,d304355574@qq.com Keywords: waste concrete, recycling, economic benefits, environmental benefits Abstract: this paper analyses the reutilization of waste concrete is feasible in technology, technical index, and its concrete recycling huge economic, environmental benefits.
In the past 10 years, the application of recycled concrete has attracted much attention in many countries, some countries have adopted legislation to ensure the development of the study and the application, mechanism of sustainable development of the world ( SRL) is to provide environmental standards for recycled concrete, and domestic and foreign research results of the regenerated basic properties of concrete have shown that can meet the performance requirements of ordinary concrete and recycled aggregate concrete, and its application in engineering structures is feasible, but on recycled concrete application of economy of doubt, therefore, the application of recycled concrete technical economic analysis is very important.
