Abstract

Chemically grouted sand is considered a two-phase particulate composite, and the mechanical properties under pure torsional loading are examined at both the particulate and composite levels. Both the adhesive and cohesive properties of grout are believed to influence the behavior of grouted sand, and an experimental program was conducted to quantify the particular relationship for each. These data, together with the porosity of the sand, are employed to formulate strength, shear modulus, and failure strain models for predicting the behavior of grouted sand from a knowledge of the properties of the constituents. The most critical mode of failure for grout and grouted sand is tension, but comparisons are also made between the shear and compressive properties.
