  Flakiness and Elongation Index Test of Coarse Aggregate

  3  · Flakiness and Elongation Index Test are very important tests to be performed on aggregate in the laboratory. This test gives the percentage of flaky and elongate aggregate present in the total aggregate sample. Aggregate shape, size, and surface texture majorly affect the properties of freshly mixed concrete more than the properties of hardened ...

  [Solved] As per IS 383-1970, the crushing value of an …

  This test is carried out to assess the strength of coarse aggregate when a compressive load is gradually applied. Aggregate crushing value = (W2/W1) × 100. where, W 1 = Total weight of the dry sample. W 2 = weight of material passing through 2.36 mm IS sieve. The aggregate crushing value for the surface course should be within 30% and for the ...

  20221228 · The “Aggregate crushing value” gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. It is the percentage by weight of crushing (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions.
