Abstract

In terms of the SANS 10100:2000 Parts 1 and 2, designers of reinforced concrete structures must base their designs on the cube strength of concrete, and SANS 5863:2006 specifies how this must be tested. The cube strength is known as the characteristic strength of the concrete and is the strength given in the material specification for the structure. It is further defined as the strength below which only 5% of the cube results may fall, i.e. it must give the designer a 95% confidence level that the strength will be achieved. Statistically, a 100% confidence level requires making concrete so much stronger than specified that it becomes economically unacceptable.
