TENSILE PROPERTIES OF CHEMICALLY GROUTED SAND.

In this study chemically grouted sand is considered as a two-phase particulate composite, and the tensile properties are examined as a two-phase particulate composite, and the tensile properties are examined at both the particulate and the composite levels. Both the adhesive and cohesive properties of the grout are seen to influence the behavior of grouted sand, and an experimental program was conducted to quantify particular relationships for each. These data, together with the porosity of the sand, are employed to formulate two strength models for predicting the tensile behavior of a grouted sand from a knowledge of the properties of the constituents. Comparisons are made between the tensile and compressive properties of grout and grouted sand.
