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 is usually tested after seven and twenty-eight days of curing, as concrete will virtually reach its expected final strength in twenty-eight days. After seven days, it will usually give two-thirds of its 28 day strength, serving as a good early indicator of its final strength. Two to three cubes are usually taken in order to measure the
