A laboratory test for determining the angularity of aggregate Available to Purchase

A convenient and reliable test has been developed for determining the angularity of aggregates. An examination of the existing methods indicated that the determination of the volume of voids in the aggregate when placed in a standard way was the most promising. Two methods, referred to as the flow-rate test and loose bulk density test, were investigated in detail. The latter test was found to be the most satisfactory and can be used in modified forms for both coarse and fine aggregates. It gives satisfactory results for both spheres and natural aggregates.
