Pendular Element Model for Contact Grouting
Foam grouting can be used to increase the strength and rigidity of unconsolidated sands. Foam grouting consists of reinforcing sands by depositing chemical grout at the inter-particle contacts in the form of pendular elements without filling the voids, contrary to conventional grouting processes, in which soil matrix is saturated with grout. This paper presents a theoretical model for characterizing the grout pendular elements in terms of degree of cementation, fill angle, and the separation distance between the particles. The model is validated by the experimental results obtained from a Resonant Column Device, and micrographs obtained from a scanning electron microscope. The experimental results closely match the results obtained from the theoretical model.
