Note 1- : For Crushed stone sands, the permissible limit on 150-micron IS Sieve is increased to 20 percent, These does not affect the 5 percent allowance permitted in 4.3 applying to other sieve size.

Note 2 -: Fine aggregate complying with the requirements of any grading zone in this table is suitable for concrete but the quality of concrete produced will depend upon a number of factors including proportions.

Note 3- : Where concrete of high strength and good durability is required, fine aggregate conforming to any one of the four grading zones may be used, but the concrete mix should be property designed. As the fine aggregate grading becomes progressively finer, that is from Grading Zones I to IV, the ratio of fine aggregate to coarse aggregate should be progressively reduced. The most suitable finer to coarse ratio to be used for any particular mix will, however, depend upon the actual grading particle shape and surface texture of both fine and coarse aggregates.

Note 4-: It is recommended that fine aggregate conforming to Grading Zone IV should not be used in reinforced concrete unless tests have been made to ascertain the suitability of proposed mix proportions.
