Answer / er. salim nagori
As per IS 456-2000
The nominal mix proportion is restricted upto M25.
So in order to achieve beyond M25, we follows mix design
calculation i.e: Design Mix
Moreover the design mix can be done for any mix
M5, M10, M15, ....... M60,and so on as per development in
technology.

Answer / neeraj
in nominal mix we consider only cement,agregate & water in
volumetric method and can achieve upto 25mpa crushing
strength .We also get big range in strength of same mix
whereas design mix we accuratetely implement reduction of
water cement ratio by use of plasicisers ,account for
desired temparature & achive strength upto 100mpa or more
