What is the difference between nominal mix and design mix?

Answer Posted / santosh agnihotri

The main difference between Nominal Mix and Design Mix is
that :-
In Nominal mix design we are considering the ratio of
ingradients like 1:1.5:3, Here no water cement ratio,Size
of agreegate, strength,durability, workability are
considered.
Where as in Design Mix apart from ingradients ratio other
factors like, w/c ratio, Size of aggregate ,workability etc
are kept in consideration while designing.

hence taking same ingradients two or more NOMINAL MIX
design may have differenth strength,
whereas in Mix design it is unlike the above.

Also the nominal mix design is less economical.
