Abstract
AbstractCalcareous sand is sedimentary soil, consisting of abundant calcium carbonate mineral or lime/chalky carbonate particles, such as shell fragments, or remains of marine organisms. The sand exhibits some special behaviours that are different from those of silica sand, e.g. relatively high specific gravity, special surface texture, irregular particle shape, local voids, and highly crushable susceptibility.Due to the high risks, hence high cost implication, involved to structures built over land reclaimed by mean of hydraulic fills of calcareous sand e.g. for the Palms of the Emirates and other artificial islands, it is crucial to study the dynamic properties of calcareous sand for e.g. liquefaction potential analysis to achieve safe and economical foundation solutions. In this paper we present and discuss on cyclic resistance and dynamic properties of a local calcareous sand obtained from various tests, including cyclic triaxial, resonant column, and advanced triaxial tests with bender elements.KeywordsCalcareous sandDynamic soil propertiesLiquefaction potential
