WebApr 8, 2024 · The flakiness index is the total weight of material passing through the gauge to the total weight of the sample. It is expressed in terms of percentage. Weigh the flaky material passing the gauge to an accuracy of at least 0.1 per cent of the test sample. The formula for flakiness index is. F.I = (Weight of aggregate passing through the slot of ... Web5.5 Discard the aggregate retained on the 7/8-in. sieve and passing the 1/4-in. sieve. 5.6 Test each particle retained on the 5/8-in. sieve by attempting to pass it through the 3/8-in. slot of the thickness gauge. 5.6.1 Create two piles of tested particles that do not pass through the 3/8 in. slot and those that pass through the 3/8 in. slot.
WebProcedure For the Test Flakiness Index of Coarse Aggregate:-. Sieve the aggregate sample with sieves specified in Table 1. Take sufficient quantity of aggregate to provide the minimum number of 200 pieces of any fraction to be tested. Then to separate the flaky materials, gauge each fraction for thickness on a thickness gauge of the pattern ... WebRough-textured, angular, and elongated particles require more water to produce workable concrete than smooth, rounded compact aggregate. Consequently, the cement content must also be increased to maintain the water-cement ratio. Generally, flat and elongated particles are avoided or are limited to about 15 % by weight of the total aggregate.
