The engineering application and development direction of Recycled Concrete

In the course of the deepening urbanization, the construction of new architectures and the demolition of old buildings will both produce a very great amount of construction waste, which will result in severe environmental pollution and waste of resources. Therefore, the recycling of the construction waste especially the waste concrete will bring about outstanding environmental and economical benefits, which will also be an important method of maintaining a sustainable development of construction, resources and environment. This paper briefly introduces the basic properties of recycled concrete and its engineering application at home and abroad. Also discusses the application prospect of composite structure and recycled concrete board. It points some directions for the use of recycled concrete.
