Webestimate the properties of the grouted sand from the constituent properties that will lead to proper selection of grouts. The compressive behavior of grouted sand will depend on the cohesive behavior of the grout, the groutsand adhesion (bonding), and the properties of the sand. The physical or chemical WebMay 25, 2024 · Grouting is considered to be a successful ground stabilisation method [ 3, 4, 5 ], which in turn helps to mitigate liquefaction and increases the shear strength. Shear strength is essential as well as a complex parameter which has different values under different field and engineering conditions.
