Evaluation of cementation effect of sand using cone …
Korea University, Seoul, Korea. ABSTRACT: In this study, the cone resistance of cemented sand is measured by per-forming a series of miniature cone penetration tests on the specimens prepared in a calibration chamber. The cementation effect is induced artificially with 5~10% gyp-sum content of sand weight. It is observed from the experimental ...
