    Abstract

    The mechanical behavior of a grouted geomaterial is influenced by both the cohesive properties of the grout and the bonding between the grout and the solid interface. Not only is the contribution of adhesion to the overall behavior not well understood, but there are no standard test methods to evaluate the adhesive properties at an interface. As one step toward better understanding this adhesive behavior, simple tests were developed to evaluate the adhesive strength under tensile, shear, and mixed mode loading conditions. Quartz rock and a grout mix consisting of sodium silicate, ethyl acetate, formamide, and water were used. Test results show that the bond strength changes with curing time and can be represented by a Mohr-Coulomb failure criterion.
