Abstract
This research examines the small strain properties of Ottawa, Monterey and Michiana sands cemented in the laboratory with two different cementing agents using flush mounted transducers, bender elements, and resonant column tests. Samples cemented with higher strength cementing agents and higher cement contents had higher maximum shear modulus values and greater nonlinearity in the shear modulus reduction and damping curves. Although confining pressure is a significant factor for the small strain stiffness of uncemented sands, it did not affect the maximum shear modulus or the shear modulus reduction curves of the cemented sands tested. The density of the cemented samples influenced the maximum shear modulus but had little effect on the nonlinearity of the shear modulus reduction and damping curves. For a given level and type of cementation, the normalized shear modulus reduction curves fell within a narrow band for the sands tested, indicating that these results could be used to predict the effects of cementation for other siliceous sands.
