Abstract:
We invent a method changing chrome residue into ceramic bone stuff. We initially manufacure bone bisque, and then ceramic bone stuff is formed at 1 200±30 ℃ high temperature and reduction condition by the rotary kiln sintering. The method has such characteristics as simplicity, economics, reliablity, good rigidity and stable structure, so it can be available to concrete recycling. Experiments show that the content of the chromium residue ceramic bone stuff is lower than 0.05 mg·L-1, and that the content of Cr6+ remains unchanged after 5 years.
Key words: chromium residue, ceramic bone stuff, comprehensive utilization
