    5/1/2021· The Aggregates which has a size of more than 4.75 mm is known as Coarse aggregate. The Aggregate sizes which range from 4.75 mm to 80 mm are the coarse Aggregates and the 150 microns to 4.75 mm aggregates are known as Fine Aggregates. The size 4.75 mm is common for both fine Aggregates as well as coarse Aggregates.

  • Aggregate Crushing Value Test Significance & Test

    The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
