| 4 | The Quality Improvement of Stony Construction and Demolition Waste (CDW)显示文摘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 Fe-2O-3 between the two materials, a wet method of jigging and a dry method of magnetic separation are effective,tested. | 邢伟宏 Alex Fraaij Hans Pietersen Peter Rem Koen Van Dijk | 2004 | Journal of Wuhan University of Technology(Materials Science)2004，19，3： | 0 |
