The measurement of particle elongation and flakiness: a critical discussion of British Standard and other methods

Abstract

Summary The author has given reasons elsewhere for recommending a more careful study of particle shape in engineering aggregates. Measurements of flakiness and elongation have long been considered important, but methods of determining these qualities both by direct measurement and by means of gauges are in need of some revision. This paper points to some of the difficulties and fallacies concerned and suggests means to overcome them.
