The aggregate size and shape, desired workability, and use of additives are major influencing factors. Table 4 of IS 10262:2019 specifies 186 kg of water for 1 cubic meter of concrete with 20 mm maximum size aggregate. The slump for this value is 50 mm. Estimated water content for 75 mm slump-. = 186 + (3×186)/100 = 191.58 kg.

For a severe freeze-thaw exposure, Table 9-5 recommends a target air content of 6.0% for a 25-mm aggregate. Therefore, design the mix for 5% to 8% air and use 8% (or the maximum allowable) for batch proportions. The trial-batch air content must be within ±0.5 percentage points of the maximum allowable air content.
