Compressive Strengths of Silicified Coarse and Fine Grained Soils
Publication: Geo-Frontiers 2011: Advances in Geotechnical Engineering
Abstract
Recent discoveries into how certain marine organisms produce their skeletons has provided inspiration for a new treatment method for creating cementation in both fine and coarse-grained soils. The silicification method offers environmental and physical advantages over some traditional methods by utilizing non-toxic, commercially available components with low potential for adverse environmental effects. Silicification begins by first pretreating the soil using a commercially available cationic polyelectrolyte which is then followed by treatment with a mixture of commercial sodium silicate and buffer. The unconfined compressive strengths of three sands and one clay were measured over a range of polyelectrolyte concentrations at a constant sodium silicate concentration of 20 percent by volume. Results indicate that polyelectrolyte type and pretreatment concentration can be optimized to significantly increase the compressive strengths of sands and clays. Review of published data suggests that compressive strengths of samples silicified by this approach are equal to or greater than strengths of samples prepared at comparable silicate contents using a variety of methods.
