Effect of natural zeolite on the shear strength of cement stabilized loess soil

Abstract

The present study intends to make an initial assessment of the effect of a natural zeolite addition on shear strength of cement stabilized loess soil. Unconsolidated undrained triaxial compression shear tests were performed for zeolite & cement-treated and cement-treated samples. It is found that the addition of natural zeolite does not reduce the shear strength of the cement stabilized loess. It causes only slight changes in shear strength parameters of non-compacted loess-cement. This allows the natural zeolite to be successfully used for an improvement of the durability, impermeability, sorption and retardation characteristics of the loess-cement.
