Study on Recycling Utilization of Waste Concrete

摘要

In the process of urban development, with the reconstruction of old city, a lot of waste concrete will be generated. At the same time, civil engineering construction, earthquakes and wars also can generate a large number of waste concrete. The existence of waste concrete will directly pollute environment and occupy the land resources. The recycling utilization of waste concrete is benefit to environmental protection and saving resources, and is also benefit to realize the sustainable development of building materials. Waste concrete research situations in China and abroad were introduced. The crushing and regeneration technology of waste concrete were studied. The material properties of recycled concrete were analyzed and some advices about development of recycled concrete in China were presented.
