Analysis and Assessment of Laboratory Strength Development in Cement Stabilized Coarse Grained Soils

Abstract

This paper deals with the formulation of a phenomenological model to assess the laboratory strength development in cement stabilized coarse grained soils with low fine fraction. Since both soil and cement are interacting materials with pore fluid, soil-water/cement ratio, w/C has been found to be an appropriate parameter in the analysis of strength development in their stabilized state. The proposed model is useful to assess the strength wherein water content, cement content and compaction energy vary over a wide range using the test result of a single laboratory trial. This capability enables to pursue the reverse process to obtain required strength of soil-cement road, consistent with the in-situ properties of the soil.
