· 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.
Concrete mix design can be a complex and time consuming process. Concrete is a very complex composite material consisting mostly of cement, water, aggregates and other property altering additives. The design of a concrete mix is extremely complicated as changing the volume or properties of any one component will affect all the others.
