Notes:

1. F.A.= FineAggregates,C.A.= Coarse Aggregates

2. The table is based on assumption that the voids in sand and crushed

stone are 40 and 45 percent respectively.

3. Air content of 1 percent has been assumed.

4. For gravel aggregates decrease cement by 5 percent, increase sand by

2 percent andcoarse aggregatein proportion to fine aggregate in mix.

4. No allowance has been made in the table for bulking of sand andwastage./>

NOTES:When both fine and coarse aggregates are poorly graded, the

following general rules regarding suitable proportioning of these will befound helpful:

1.For maximum size of coarse aggregates as 40mm and over, sand

should be half as much as coarse aggregates.

2.For maximum size of coarse aggregates as 20mm and over, sand

should be two-thirds as much as coarse aggregates.

3.For maximum size of coarse aggregates as 16mm, sand and coarse

aggregates should be in equal parts
