HOW TO CALCULATE WATER CEMENT RATIO The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio.

It has no specific answer because cement content depends upon maximim size of aggregates which in turn depends on water content. According to current industrial practise for M20 grade minimum 320 -340 kg of cement is used which results in 6-7 bags for RCC. For PCC work 5-6 bags would be sufficient and economical.

This formula will give you the estimated cubic yardage needed to do your project. For example if you have a concrete slab 24' L x 24' W x 6" thick, the formula would read like this; 24 x 24 = 576 x .5 = 288 divided by 27 = 10.67 cubic yards. (make sure you change the inches thick to feet, 6 inches thick = .5 feet)
