Preparation of artificially frozen sand specimens
Several specimens of artificially frozen sand (ASTM C-109) were prepared to evaluate different testing procedures and techniques used to determine the mechanical properties of frozen soils. Two methods of preparation of fully saturated frozen sand specimens, described by other investigators, were co...
