For large scale constructions standardgrade highgrade concrete like M25 M40 M45 M50 etc are used. There is a requirement for design mix in highgrade concretes.

### Difference Between Nominal Mix and Design Mix

A nominal mix is a mix that takes into account the strength and cost of concrete and all volume ratios of concrete with different strengths. The design mix is a mix with constant concrete strength and a weight ratio for all mix ratios. You can reduce tangible costs. Used for ordinary concrete with a concrete grade not exceeding M20.
