A series of laboratory tests were performed on the dredged clays treated with quick lime to investigate the main factors of effect on their unconfined compressive strength. The relationships between unconfined compressive strength of treated dredged clays with quick lime and original water content of dredged clays

quick lime content

and water content of treated soils were discussed. Analysis of test data gave a linear relationship between the unconfined compressive strength of treated dredged clays with quick lime and the decreasing percent of water content proposed by authors. A quantitative formula was also proposed in this study for predicting the unconfined compressive strength of treated dredged clays with original water content of dredged clays and water content of treated soils. The testing results are valuable for utilization of waste dredged clays as filling materials.
