Abstract: The present invention provides the compositions and processing methods of an environmental-friendly, multiple-effect powder. The compositions of environmental-friendly, multiple-effect powder include: cement, discarded PCB powder, resin, wasted coating powder and volcano mud powder. The environmental-friendly, multiple-effect powder of the present invention can also be widely applied to civil works as a coating/filling material or other composite building materials due to its advantages such as good thermal insulation, noise absorption, water-proofing, resistance to mildew, rustiness and acid/alkali, excellent robustness and moisture retention with better industrial and economic benefits.
