Theoretical Derivation of Artificially Cemented Granular Soil Strength
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 143, Issue 5
Abstract
This paper provides a theoretical derivation for the unconfined compression strength of artificially cemented granular soils. The proposed developments are based on the concept of superposition of failure strength contributions of the soil and cement phases. The granular matrix obeys the critical state soil mechanics concept, whereas the strength of the cemented phase can be described using the Drucker-Prager failure criterion. In the process, the analytical relation is suitably adjusted to parallel a recently proposed empirical relationship that links unconfined compression strength of artificially cemented granular soils to an adjusted porosity/cement ratio parameter. Although the proposed analytical relation fits the experimental data for different granular soils and cement curing time well, further parametric analysis offers the possibility of exploring the effect of some material parameters on the unconfined compression strength of artificially cemented granular soils.
