Grading is the distribution of particles of a granular material among various size ranges, usually expressed in terms of cumulative percentage larger or smaller than each of a series of sizes of sieve openings, or the percentage between certain range of sieve openings. ASTM C-33 grading requirements for coarse and fine aggregates.

Fine aggregate River sand. The natural river sand obtained from local sources conforming to the zone II grading of Table 3 of IS:383-1970 was used as fine aggregate in the present study.The shape of grains was cubical or rounded in nature with a smooth surface texture; hence, a good workability of concrete was ensured.

Bulking of Fine Aggregate The test was conducted according to the procedure laid down in IS 2386(PART III): 1963. Bulking is an intrinsic property of natural sand. This is very important property in volume batching of aggregate. The test results are given in table 2 and table 3 for natural and manufactured sand.

Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.
