Abstract The image analyzer commonly used by the powder metallurgists has been successfully employed to quantify angularity and shape characteristics of granular materials. In this paper a detailed procedure has been outlined. Results of investigation of different natural sands are presented in the form of a distribution of tangent count taken as a measure of angularity. Powers' roundness index has been calibrated against the tangent count. Mechanical properties of different sands have been shown to be correlated with angularity.
