To find the design mix ratio, divide the calculated value of all materials by the weight of the cement. Therefore the Mix Design Ratio of M25 Grade concrete by weight is Cement: F.A: C.A: Water = 1: 1.9 :3.1 : 0.50. Note: This is a Design mix ratio by weight which is different from the Nominal volumetric mix ratio.
As per IS 456 : 2000, Nominal mix of concrete is given below. In industrial and infrastructure development, to serve the requirement for high strength concrete and …

Concrete mix design – M70 grade of concrete provided here is for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the location and other factors. Characteristic strength given by the relation 70 + (1.65 *5 ) = 78.25 N/mm 2. 20 Mm = 24, 10 mm = 36, r/sand = 20, c/sand = 20. Aggt: cement = 2.82 : 1.

The aggregate size and shape, desired workability, and use of additives are major influencing factors. Table 4 of IS 10262:2019 specifies 186 kg of water for 1 cubic meter of concrete with 20 mm maximum size aggregate. The slump for this value is 50 mm. Estimated water content for 75 mm slump-. = 186 + (3×186)/100 = 191.58 kg.
The grade of concrete has been specified by IS 456 : 2000. But the limitation of IS code is that it specifies the concrete mix ratio up to a certain grade, which is M25, above which no certain mix proportion has been approved in industrial and infrastructure projects. As per IS 456 : 2000, Nominal mix of concrete is given below.
Substituting the values in Eq(1), we get 1000 = 185 + 394/3.0 + (1/0.38) * fa /2.6) fa = 675 Kg. Substituting the values in Eq(2), we get 1000 = 185 + 394/3.0 + (1/0.62) * ca /2.65) …

For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are either by volume or by mass. The water-cement ratio is usually expressed in mass.
The Concrete mix design is as per Indian Standards (IS 10262) and might vary from country to country. The nominal mix design ratios available for concrete less than M30 in strength are only thumb rules and are generally over designed. As the actual site conditions vary and the mix design should be adjusted as per the location and other …
