Total Aggregate by cement ratio (A/C) decreases with increase in grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30 Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio.
