Abstract

In order to evaluate the effects of cementation on the mechanical properties of cement-treated soil, a series of isotropic consolidation and undrained triaxial compression shear tests were performed for cement-treated specimens of Ariake clay, Akita sand, Rokko Masado and Toyoura sand. This paper evaluates factors affecting the shear strength of these cement-treated soils. The following conclusions are obtained: 1) Cement-treated soil has a normally consolidated line in e-ln p′ space which depends on the mixing cement content. The consolidation yield stress, p′y of cementtreated soil increases with increasing cement content and initial specimen density. 2) Changes in cohesive strength due to cement-treatment can be represented by a tensile effective stress, p′r. Strength properties can then be normalized by the augmented consolidation stress, (p′c+p′ r). 3) The shear strength properties of quasi-overconsolidated clay can be represented by the yield stress ratio, R = (p′y +p′r)/(p′r+p′r). 4) The undrained shear strength of cement-treated soils can be represented as a power law relation of the yield stress ratio, R, and the augmented consolidation stress.
