Undrained shear strength and liquefaction potential of loose silty sand treated with microfine cement

摘要

The objective of present paper is to evaluate the effect of cement grouting on undrained shear strength and liquefaction potential of silty sand. For this purpose, triaxial undrained compression tests are performed on silty sand sample with different amount of silt content (0 - 30 %), treated with microfine cement. The results indicate that, cement grouting significantly improves the physical and engineering properties of soils, which can result in increased shear strength of silty sand.
