Strength of RCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton's per millimeter Cubed) compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8.
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.

Hence, to prepare 1 cubic meter of M20, M15 and M10 concrete, 1.57 cubic meters of "total dry volume" of cement, sand and aggregate are needed, whereas to prepare 1 cubic meter of M7.5 and M5 concrete, 1.52 cubic meters of "total dry volume" of cement, sand and aggregate are needed. Many websites are giving different values for the "total dry volume" of the ingredients.

There are different grades of concrete like M15, M20, M25, M60, etc. For small-scale constructions; normal grade concretes like M10, M15 & M20 are used. For large scale constructions; standard-grade & high-grade concrete like M25,M40, M45, M50, etc are used. There is a requirement of design mix in high-grade concretes. {Note: In M20 grade concrete

Incase you want to convert the requirement of Sand and Aggregate in Cum; 1 Cum = 35.31 Cft Eyeopener:Many popular blogs claim M20 nominal mix as 1:1.5:3,however we strongly differ by same.Through this blog,we are also trying to address the same myth which is being carried forward since last 4 decades.. The reason being: With constant research and development in the field of cement …
1.Mixing ratio details for bricks manufacturing using these raw materials. Fly ash (55-60%). River Sand or stone dust (20-25%). Sludge Lime (15-22%). Gypsum (5%). NOTE :- Sludge Lime is economical than Hydrated Lime, this mixing ratio is the best and more profitable than other two ratios listed below.
M15 = 1:2:4 M20 = 1:1.5:3 M25 = 1:1:2. Designed Concrete Mix/Ratio. The proportion of the material is determined by the concrete mix expert in this method. In design mix the concrete production is with appropriate properties. In Design mix there is no guide for right mix proportions it follows the economical method as per the requirement.
The grades of concrete are converted into mix proportions consider for M20 concrete mix proportion will be 1: 1.5: 3 (cement, sand and coarse aggregates). Suitable Concrete Grade For Construction: Based on structural design requirements the grade will be selected and there are two types of concrete mixes, design mix & nominal mix.
