The DOE method was first published in 1975 and revised in 1988. The DOE method of mix design is applicable to all types of concrete mixes including roads, while Road Note No. 4 was applicable to roads and air fields only. This method can also be used for concrete containing fly ash. DOE method is a standard method of mix design in U.K. now.

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 M30 concrete mix ratio is a proportion of ingredients used to achieve a particular strength in concrete. The ratio is 1:0.75:1.5, which means for every 1 part cement, you need 0.75 parts sand and 1.5 parts aggregates when making 1 cubic meter of concrete. For Concrete mix design, we use, IS 456, and IS 10262.

Concrete strength is expressed in the units N/ mm 2 . 1 N/ mm 2 = 1 MN/ m 2 = 1 MPa. (N = newton; Pa = pascal.) The internationally known term 'relative density' used here is synonymous with 'specific gravity' and is the ratio of the mass of a given volume of substance to the mass of an equal volume of water.
