Concrete has been around for hundreds of years, giving builders endless possibilities to design strong and attractive structures that are able to last several lifetimes.  In practice concrete is the perfect building material. It is cheap and readily available, can be formed into nearly limitless shapes, sets as hard as stone and has the structural strength to support high rise buildings. In large-scale construction projects users even have the ability to order it ready-mixed and simply pour it where it is required – quick and easy.

Readymix concrete is a sophisticated, engineered material made from constituents that vary in different mixes and it is delivered and placed before all its properties can be proven, such as its 28-day comprehensive strength. Each readymix plant can supply diffent concretes and the quality of all of these has to be controlled. The use of control charts, concrete families and the prediction of the 28-day strength from early test data are part of the normal quality control processes employed in the production of concrete in SA. However, it is important that such sophisticated systems should be assessed by independent experts to determine whether they have been set up correctly and are being applied correctly.
