Abstract

The effects of stress history and relative density on the short-term strength and stiffness of a granular soil (Ottawa 20-30 sand) that was chemically stabilized with a sodium silicate grout were investigated. A system was developed to inject grout into sand specimens that were prepared in a triaxial cell; the specimens were subjected to a confining stress of 360 kPa and grouted under a pressure of 144 kPa. The results are analyzed in terms of Mohr-Coulomb failure theory, and comparisons are made among the compressive strength, initial tangent modulus, angle of internal friction, and cohesion of the specimens for different test conditions.
