To calculate the mix design for M25 concrete, you typically follow the guidelines provided by the Indian Standard (IS) 10262:2019. The design involves determining the proportions of cement, aggregates, and water based on the desired strength, which is 25 MPa for M25. A common mix ratio for M25 is 1:1:2 (cement:sand:coarse aggregate), but adjustments may be made based on specific project requirements and material properties. It's also essential to consider factors like water-cement ratio, workability, and environmental conditions when finalizing the mix.
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.
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.
40 20 concrete design mix is the water to cementitious materials ratio. This is what determines the class of the design mix.

There are 31 Junctions on the M25
It is inside the M25.
The M25 is 31 years old
The M25 is Approximately 118 Miles long.
Terminal 5 is actually on the M25. All of the other terminals are on the M4 which is just off the M25.
In one cubic meter of M25 concrete, there are approximately 13.33 bags of 50 kg each. This is based on the standard mix proportion of M25 concrete, which uses 1 part cement, 1 part sand, and 2 parts coarse aggregates by volume.
