Notes: 1. F.A.= Fine Aggregates, 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 and coarse aggregate in proportion to fine aggregate in mix. 4. No allowance has been made in the table for bulking of sand and wastage./>
