Nominal Mix and Design Mix of Concrete: Know the Difference. The nominal mix is the prescriptive type concrete because a proportion is predecided. 02. It is easy to make at the construction site. 03. It doesn''t take much time to decide the proportion because proportions are already given by standard code. 04. No need to get skilled persons for ...

Design mix concrete is preferred to nominal mix. If design mix concrete cannot be used for any reason on the work for grades of M-20 or lower, nominal mixes may be used with the permission of engineer-charge, which however is likely to involve a higher cement -in content. Accordingly all concrete of above M-20 Grade for RCC work must be of design mixes. The code allows nominal mix for RCC work ...

When the concrete is produced by taking standard arbitrary proportions of concrete ingredients, it is known as nominal mix concrete. This method is generally used when the quality control requirement for design mixes are difficult to execute.
