E.g., M15(1:2:4), the quantity of cement, sand (fine aggregate), and coarse aggregate are batched in volume as per the fixed ratio 1:2:4. From the above table till M25 grade, these concrete proportions are called as Nominal mix concrete.
Get Price"M" stands for "mix". Mix represents concrete with designated proportions of cement, sand and aggregate. And the number following "M" represents compressive strength of that concrete mix in N/mm 2 after 28 days. For example, for M20 grade of concrete mix, its compressive strength after 28 days should be 20 N/mm 2.

Get Pricecement sand and aggregate mix ratio in concrete :- there are two types of mix ratio in in different grade of concrete 1) nominal mix & 2) design mix. Nominal mix concrete IS456 code book suggest lower and normal grade of concrete like M25,M20,M15,M10,M7.5 & M5 have fix cement sand and aggregate ratio.
Get PriceFor making concrete we use cement, sand, aggregate, and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression test. The compressive stress result is known as "grade of concrete'. It is expressed in N/mm²

Get PriceWhat Is M25 Grade? It is a grade of concrete that would achieve a compressive strength of 25 N / mm 2 after 28 days of curing. It is made by mixing cement, fine aggregates and coarse aggregates in a 1: 1: 2 ratio, keeping the water-cement ratio between 0.4 and 0.6. What Is M30 Grade?
Get Price9/12/2018· And in counties like USA Grade of concrete denoted by, C15, C20, C25, C30 & C35 etc. A concrete of Grade C25 means that the concrete will have a compression resistance of 25 N/mm2 per square millimeter in 28 days. Proportion for grade C20. C20 is 1:2:4(1 part cement, 2 parts fine aggregate, and 4 parts coarse aggregate.)
Get PriceFor Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume
