This Indian Standard was adopted by the Indian Standards Institution on 30 July 1982, after the draft finalized by the Cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council. Considerable need has been felt for formulating standard recommendations for guidelines on proportioning of concrete mixes. The need has been further emphasized by the importance given to design mix concrete according to IS : 456-1978*. Having recognized this need, Cement and Concrete Sectional Committee decided to evolve a standard recommended guidelines for concrete mix design. 043 The proportioning of concrete mixes consists of determination of the quantities of respective ingredients necessary to produce concrete having adequate, but not excessive, workability and strength for the particular loading and durability for the exposure to which it will be subjected. Emphasis is laid on making the most economical use of available materials so as to produce concrete of the required attributes at the minimum cost, Concrete has to be of satisfactory quality in both the fresh and hardened states. The task of proportioning concrete mixes is accomplished by the use of certain established relationships which afford reasonably accurate guidance for selecting the best combination of ingredients so as to achieve the desirable properties of the fresh and hardened concrete. Out of all the physical characteristics of concrete, compressive strength is often taken as an index of its quality in terms of durability, impermeability and watertightness and is easily measurable. Therefore, the mix design is generally carried out for a particular compressive strength of concrete, coupled with adequate workability, so that the fresh concrete can be properly placed and compacted. In addition, the mix proportions are also checked against the requirements of adequate durability for the type of exposure condition anticipated in service. The basic assumption made in mix design is that the comprrssive strength of workable concrete is, by and large, governed by the watercement ratio. Another most convenient relationship applicable to normal concretes is that for a given type, shape, size and grading of aggregates, the amount of water determines its workability. However, there are various other factors which affect the properties of concrete, for example, the quality and quantity of cement, water and aggregates; batching; transportation; placing; compaction; curing; etc. Therefore, the specific relationships that are used in proportioning concrete mixes should be considered only as a basis for trial, subject to modifications in the light of experience as well as for the particular materials used at the site in each case. This standard does not debar the adoption of any other accepted methods of mix design. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
