Method of Nominal or prescribed mixes is generally adopted for small jobs where cost exercising quality control is not Justifiable. This method of concrete mix design. Indicates the normal mix proportions for ordinary concrete recommended by Indian Standard Code 456-1978 for the compressive strength range for — at 28 days.

In the nominal mix concrete, all the ingredients and their proportions are prescribed in the standard specifications. These proportions are specified in the ratio of cement to aggregates for certain strength achievement.

Nominal Mixes can be adopted only upto the grade of M20, but above m20 grade, a concrete must be mix designed as per code provisions. Though most of us uses Nominal mix of 1:1:2 for M25 Grade, but it shouldn’t be done.

The nominal mix proportions varies based on the zones of sand and size of the course aggregates, so its batter to get with the design mix, But the mix design of concrete cannot be used for any reason on the work for grades of M-20 or lower than the M-20.

This means that we produce concrete that complies with the guidelines set in the European Standard and the British Standard parts 1 and 2. Concrete that is produced to this standard is deemed not to contain harmful ingredients in quantities that could affect the durability of the concrete or potentially corrode reinforcements.

Read:- Simple Mix Design of M30 grade concrete with Mineral Admixture and superplasticizers. Nominal Mix Concrete. Nominal Mix Concrete is prepared by using Concrete Mix Ratios or from the Weight Approximations given in the codebook. In Concrete Mix ratio method, quantities are calculated in terms of volume.

Mix design can be divided into following two categories. 1. Design mix concrete and 2. Nominal mix concrete. 1. Design Mix Concrete: When the proportions of concrete ingredients are decided by adopting certain established relationships ( based on assumptions from a lot of experiments) to produce the concrete it is known as design mix concrete.

Cement concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Classification of concrete mixes:- The cement concrete mixes should be as per (IS: 456-2000). Concrete is generally classified by the method adopted for determining the proportions of cement, aggregate and water either as design mix concrete or nominal mix concrete.
