The results of an extensive study conducted to evaluate the effect of geometrical grain characteristics on the packing behavior of quartziferous sands from diverse environmental origins are described. Grain size is defined by mechanical sieving, and particle shape is quantified in terms of sphericity and roundness. Standard charts were used in conjunction with observations by means of a standard monocular microscope to estimate the sphericity and roundness of representative groups of grains; for a given sieve portion of a given sand, a mean value of each shape parameter was determined from a group of four samples with 25 particles in each sample.
