Abstract

A new way of treating the waste clays into a useful fill material by adding quick lime is proposed in this paper. A series of laboratory tests were performed to investigate the behavior of dry density of the quick-lime-treated-dredged-clays. The effects of quick lime contents and initial water contents of dredged clays on dry density of quick-lime-treated soils are discussed. The relationship between dry density and water content is also analyzed and compared for both the air-dried original dredged clays and the quick-lime-treated soils. With introducing a new concept of increasing percent of dry density, the law on variation of dry density of quick-lime-treated soils is proposed. That is, the increasing percent of dry density has the same linear relationship with quick lime content for different initial water contents of dredged clays. In addition, this paper also suggests a simple method of predicting the dry density of treated soils, therefore the amount of test work can be greatly reduced.
