Abstract
Slag-clay mixtures, a mixture of steel slag and dredged clay generated from port improvement projects, have self-hardening properties. Therefore, the strength properties of slag-clay mixtures are evaluated in terms of unconfined compression strength, even at sites where confining pressure is applied. In this study, the consolidated and undrained triaxial compression tests were conducted on several slag-clay mixtures with different slag addition rates and cured them for 28 days, in order to investigate the relationship between the unconfined compression strength of the solidified slag-clay mixtures and the consolidated and undrained triaxial compression strength. The following findings were obtained from this experiment and discussion. The failure points obtained from the consolidated and undrained triaxial compression tests of the solidified slag-clay mixtures after 28 days of curing with unconfined compression strengths between 50 and 2000 kPa, when normalized by their consolidation yield stresses or unconfined compression strengths, were located into a narrow range, respectively. These relations are presented by two lines, and these are separated by the consolidation stress over consolidation yield stress and unconfined compression strength, respectively.
