The Quality Improvement of Stony Construction and Demolition Waste （CDW）
摘要
Worldwide construction and demolition waste (CDW) is currently dumped. To close the building cycle and the building materials cycle by recycling CDW in high technical applications, the technical quality of stony materials must be improved. For this purpose, concrete rubbles and brick rubbles, the two major stony constituents of CDW, should be separated from each other. Based on the differences in density and content of Fe2O3 between the two materials, a wet method of jigging and a dry method of magnetic separation are effective,tested.
