摘要

In Taiwan a de-sulferization slag of about 500,000 ton is generated every year, but the recycling amount is very slight. A new approach, the cold-pressing technique incorporating the principles of the cement chemistry and composite material, was not only able to recycle innocuous construction residual soil, sludge, and sediment, but also stainless steel reductive slag with poor volume stability as recycling coarse aggregate. And the main difference between the cold-pressing and sintering technique is the reduction of energy consumption and CO2 emission. Consequently, this study mainly looks forward to recycling nonmagnetic material from de-sulferization slag as coarse aggregate through the cold-pressing technique. Herein the mixture proportions with w/cm = 0.20, a cement amount of 100 kg/m3, and more than 70% (by weight) of nonmagnetic material from de-sulferization. The test results show that the basic properties of recycling coarse aggregate conform to ASTM C33. Therefore the cold-pressing technique is a new and practicable approach to recycle nonmagnetic material from de-sulferization slag in the future.
