Coarse Aggregate(Gravel) Classification of Coarse Aggregate Uncrushed gravel or stone which is the result of natural disintegration and crushed gravel or stone are usually called the "Coarse Aggregates". As mentioned earlier, coarse aggregates are stones that are retained on sieve.

WATER ABSORPTION This test helps to determine the water absorption of coarse aggregates as per IS: 2386 (Part III) – 1963. For this test a sample not less than 2000g should be used.

The function of the coarse aggregate is to act as the main loadbearing component of the concrete. >Fine aggregate: Aggregate passing () sieve and predominately retained on the (75µ) sieve. The fine aggregate serve the purpose of filling all the open space in between the coarse particles. 4 5.
