08-04-2021· The presence of elongated particles in the aggregate is undesirable for construction. Also, this shape test is made in coarse aggregate. The elongation shape test is not applicable for aggregates with a smaller size than 6.3 mm. For finding the flakiness index, we have to test at least 200 pieces of any fraction.crushing and flakiness materials.doc - TITLE DETERMINATION,,View crushing and flakiness materials.doc from ME MISC at MARA University of Technology.

Theory The size of aggregate generally determine the way it behaves when used in concrete mixes. Ideally, a piece of aggregate has to have an equal size in all three dimensions. Due to the random nature of the stone crushing process, not all aggregate pieces are similar in size. Flakiness is a condition when the thickness of a piece of aggregate is less than 0.6 of itsInfluence of Crushing Size of the Aggregates on Dense,,found that, in Jaw crushers flakiness index increases with decrease in size of aggregate produced1 (maximum between 12.5 to 6.3 mm sieve size).
