Flakiness Index Test on Aggregates for Shape

28/04/2016· Flakiness index test is used to determine the particle shape of the course aggregate. The particle shape of the aggregates is obtained by the percentages of flaky and elongated particles accommodate in it. For base course and construction of cement concrete types, the presence of flaky and elongated particles are considered undesirable. It causes inherent weakness with possibilities of breaking down under heavy loads. Therefore, the evaluation of the shape
