Stress-strain behavior of remoulded cement-treated Singapore marine clay

Abstract

Cement stabilization has been widely used for improving the strength and stiffness of soft clayey soils. This paper reports an investigation into the stress-strain behaviour of remoulded cement-treated Singapore marine clay. A procedure was developed to prepare the remoulded cement-treated soil specimens. The remoulded cement-treated soil specimens with different mix proportion, curing time and curing stress were tested under triaxial condition. The results showed that the stress-strain behaviour is mainly dependent on the cement content and similar to that of remoulded marine clay. The compression index of remoulded cement treated soil specimen is much lower than that of intact cement-treated soil specimen and close to that of remoulded untreated soil specimen. The friction angle of remoulded cement-treated soil at the critical state is much higher than that of remoulded untreated soil. © 2011 Taylor & Francis Group.
