190 L. To find the design mix ratio, divide the calculated value of all materials by the weight of cement. Therefore 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.

F'ck = fck + factor based on grade of concrete mix design for m50, whichever is higher For concrete mix design for m50 Factor based on grade of concrete = 6.50. Standard Deviation = 5.00 F'ck= 50 + 1.65 X 5 = 58.25 N/mm2. F'ck = 50 + 6.5= 56.50 N/mm2. Hence higher value of F'ck = 58.25 N/mm2 is to be used for design calculations.

Standard mixes: As per IS 456-2000 standard, there are different types of grades for the concrete mixes which range from M10, M15, M20, M25, M30, M35 and M40. The letter M stands for the Mix and the number to the stated 28 day cube compressive strength of the mix in N/mm2.

For example, its compressive strength after 28 days should be 20N/ mm2 for concrete mix grade M20. Different Grades of Concrete. Various cement types have different proportions of Cement Mix, meaning different concrete mixing ratios. The Concrete mix model has the following concrete mixing ratios as per IS456:2000.
