IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. For this reason, the minimum compressive strength has been included in many specifications. The nominal mixes of fixed cement-aggregate ratio (by volume) vary widely in strength and may result in under- or over-rich mixes. However, due to the variability of mix ingredients the nominal concrete for a given workability varies widely in strength. These offer simplicity and under normal circumstances, have a margin of strength above that specified. These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates.

The requirements which form the basis of selection and proportioning of mix ingredients are :Ī ) The minimum compressive strength required from structural considerationī) The adequate workability necessary for full compaction with the compacting equipment available.Ĭ) Maximum water-cement ratio and/or maximum cement content to give adequate durability for the particular site conditionsĭ) Maximum cement content to avoid shrinkage cracking due to temperature cycle in mass concrete.

The cost of labour depends on the workability of mix, e.g., a concrete mix of inadequate workability may result in a high cost of labour to obtain a degree of compaction with available equipment. The extent of quality control is often an economic compromise, and depends on the size and type of job. This depends on the quality control measures, but there is no doubt that the quality control adds to the cost of concrete. The actual cost of concrete is related to the cost of materials required for producing a minimum mean strength called characteristic strength that is specified by the designer of the structure. From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. The variations in the cost of materials arise from the fact that the cement is several times costly than the aggregate, thus the aim is to produce as lean a mix as possible. The cost of concrete is made up of the cost of materials, plant and labour. quality and quantity of cement, water and aggregates batching and mixing placing, compaction and curing. The compressive strength of hardened concrete which is generally considered to be an index of its other properties, depends upon many factors, e.g. The property of workability, therefore, becomes of vital importance. If the plastic concrete is not workable, it cannot be properly placed and compacted. The proportioning of ingredient of concrete is governed by the required performance of concrete in 2 states, namely the plastic and the hardened states. The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design. Mix design for self compacting concrete is given as below.

As there is no indian code available for self compacting concrete mix design, it is designed based on EFNARC specifications.
