Natural Curing (Exposed concrete) 1. Water Curing. The application of the water is done to avoid the drying of the concrete surface. Usually, this method applies when the concrete is thinner. For example, in building construction, the curing of the floor slab can be done with this method. There are two methods to apply the water on concrete.

In some extreme cases, many cubes are taken, and the tests carried out every few days, but as a general rule, the 28-day strength is taken as the target. For some concrete not reaching the desired 28-day strength, the crushed cube remains are submitted for chemical testing to confirm the cement content and water/cement ratio.

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 strength of concrete is generally measured by testing concrete cubes which are prepared from the concrete used in that particular construction. The cube strength of concrete is specifi ed by a structural engineer and is assessed by crushing concrete cubes at a specifi ed age (28 days after casting).

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
