SOLIDIFIER ARTIFICIAL SOIL CONTAINING CALCIUM CHLOROALUMINATE

摘要

PURPOSE: A solidifying material for artificial soil is provided to prepare high quality artificial soil by solidifying sewage sludge in order to satisfy the moisture content of the sewage sludge and the strength for artificial soil and to improve work environments. CONSTITUTION: A solidifying material for artificial soil containing calcium chloroaluminate mineral includes, based on 100 parts by weight of a solidifying object, 5~10 parts by weight of quicklime, 5~15 parts by weight of calcium chloroaluminate mineral, 5~10 parts by weight of heavy metal absorbents, 0.1~2 parts by weight of citric acids or tartaric acids and 5~10 parts by weight of illite powder. The heavy metal absorbent uses the clean water sludge in which an absorbing membrane is formed on the surface by controlling the Al/Si mole ratio of 1~1.5, wherein the clean water sludge has the particle size of 4,000~6000 cm^2/g and the water content of 3~7%.
