In IS:10262-1982, cl.3.3.4 & table-6 says +/- 3 percent adjustment is required in the quantity of water (calculated as per table-4 or 5), for each increase or decrease in the value of compacting factor (i.e. workability of concrete) by 0.1. How it is possible to calculate the exact quantity of water required for a particular grade of concrete? What is the relation between Slump & Compacting factor of concrete?
