Abstract: A certain amount of chlorinated residue was produced in the titanium tetrachloride production process by chlorination technology.This research adopted the cement solidification method to deal with chlorinated residue.Through systematical condition experiment，the influences of curing time，and mixed amounts of fly ash，silica fume，and chlorinated residue on leakage rates of harmful components were investigated.The single factor experiment showed that the optimal experimental conditions were as follows：40 d of curing time；mixed amounts of fly ash，silicon powder，and chlorinated residue were about 20%，10%，and 10%（mass fraction，same below)，respectively. Through the orthogonal experiment the optimal chlorinated residue curing formula was obtained: fly ash of 20%，silicon powder of 8%， and chlorinated residue of 8%.The curing effect order of the three mixed amounts was as follows: chlorinated residue >silicon powder>fly ash.

Key words: chlorinated residue, curing, leakage rate
