Nominal mix and design mix are the two types of concrete mixtures. The nominal mix is appropriate for routine construction projects, such as small residential buildings. The ratio of 1:2:4 is the most popular nominal combination. The mix proportions for design mixed concrete are determined by several lab experiments on a cylinder or cube for ...

2. Standard Mix Concrete Ratio. Nominal admixtures of fixed cement-aggregate ratios (by volume) vary widely in strength and may result in more or less rich admixtures. For this reason, minimum compressive strength is included in many specifications. These mixtures are called standard mixtures.. IS 456-2000 designates concrete mixes in several grades as M10, M15, M20, M25, M30, M35, and M40.

In Nominal mix ratio of different material are already defined while in the design mix ratio is defined after the testing with different trial mixes. Grade of concrete are such as as M10, M15, M20, M25, M30, M35 and M40 e.t.c. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2.
