Abstract

This chapter presents a comprehensive study of the geotechnical properties of transparent amorphous silica powders including shear strength, permeability, and consolidation. The stress-strain behavior under both normally consolidated and over consolidated conditions are similar to those of natural clays. The shear strength parameters and permeability of this material are within the reported values for natural clays. The consolidation behavior of transparent amorphous silica is similar to that of natural peat and organic clays, where secondary consolidation dominates the behavior. The material can be consolidated at various pressures to meet specific model test requirements in terms of strength, deformation, and permeability. It provides an excellent media to simulate macroscopic deformation and flow in clays using an optical set-up.
