Abstract:Direct methods of estimating particle shape become lengthy if a truly representative sample of a sand is to be examined and are therefore unsuitable for routine use. Thus indirect methods have been developed in which a bulk property of the material, which is strongly influenced by grain shape, is measured in a standard test. The purpose of the work reported in this paper was to seek a correlation between shape parameters obtained by direct examation of individual grains and those derived from simple bulk tests. This work has resulted in a quick reliable method of estimating grain shapes of natural silica sands from a flow rate test.
