- Abstract
- The report evaluates the beneficial effects of artificial cementation in modifying loose sandy soils to safeguard against earthquake induced damage. The study has increased the data base of properties of uncemented and artificially cemented sands at different strain levels. Results indicate that unconfined compressive strength, tensile strength, shear strength, and deformation modulus increase considerably with cementation. The dynamic behavior of cemented sands was found to be greatly influenced by cement content and density and it was demonstrated that a small amount of cementation significantly increases the liquefaction resistance of uncemented sands. The data base was used to develop or modify relationships for deformation modulus, maximum dynamic shear modulus, dynamic shear damping, dynamic longitudinal moduls, etc. for use by practicing engineers.
