- Rapid and rough economic development in southeastern China has led brownfields come to be big problems. In this study, heavy metal contaminated soil and sludge were used as raw materials for ceramsites making in a simulated calcination system. Different recipes of raw materials for ceramites making were estimated by physical properties, heavy metal releasing risk. The results suggested lightweight ceramsites obtained under the recipe of "30% municipal waste sludge and 70% contaminated soil" and "30% chemical sludge and 70% contaminated soil". Leaching amount of heavy metals decrease more than 80% after calcinated. However, releasing risk of heavy metal still exist both in the flue gas and ceramites.
