upto M25 it is nominal mix but after that are the design mix which need to becalculated.....
10.94 bags
For nominal Mix Cement consumption for M25 will be 570 kg per cum. and for Design Mix it can be optimised to 510 kg per cum.
40 20 concrete design mix is the water to cementitious materials ratio. This is what determines the class of the design mix.
There is no fixed rule for this. If manual mix, cement content shall vary between 350 ~ 400 Kg / M3. Where as for Design mix (RMC), the cement content is decided by the supplier based on lot of other parameters and achieve the desired strength in 3, 7, 15 & 28 Days. Also PFA (Portland Fly Ash) shall also be added to some extent to arrive the desired strenth. The Cement & Fly Ash content shall be 300 / 80 kg per M3, to achieve the desired strength.
