Strength and stiffness of Hong Kong marine deposits mixed with cement
Year: 1998
Type: article
Abstract: In this paper, test results of cement treated soft marine deposits (M.D.) from a Hong Kong coastal site are presented and analysed. The M.D. was mixed with Portland cement at different cement/soil ratio (Aw) in dry mass and at different initial water content (wi) of the soil. Unconfined compression tests and consolidated undrained triaxial tests were conducted. Stress-strain-strength characteristics of the cement treated M.D. are investigated. Useful relationships are obtained for peak strength (qpeak), residual strength (qres), cohesion and friction angle (c′, φ′) and Young's modulus (E50) as related to Aw and wi. The effectiveness of the cement treatment is investigated. Conclusions are drawn on (a) the specific application of the improvement of Hong Kong marine deposits using cement, (b) the general trends of the stress-strain-strength characteristics of cement treated soft soils and (c) the effectiveness of soil improvement using cement treatment.
