In IS:456-2000 the workability of concrete is given in mm (slump)in cl.7.1. 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?

As per Kandal suggestions, we have implemented rolling starts on 140 (+/- 5) degrees and we kept 3 rollars to complete the rolling before falling 125 degrees and the Aggregate AIV is below 22. But When the DBM bed is being rolled 3rd high viabration, (Before 1 plain & low ,2 high Viabrations), the aggregate is getting sharp edge agg. projections are damaged. As the literature is said that, the VG-30 Grade having better control the temp. susceptibility than Penetration grade. if so we could not get this problem at site. But we are facing on site. let me know.
