The Prediction of Crack Widths in Hardened Concrete

A requirement to check the widths of load-induced cracks is now a feature of current British Codes for structural concrete. However, the theoretical background to the procedures given in the Codes has not been published in a readily available and reasonably condensed form. This paper attempts to rectify this situation by presenting the derivation of a theory for the prediction of cracking in hardened concrete. This theory is shown to be a logical development of earlier theories, and is based on the extensive research program carried out at the Cement and Concrete Association over the last 14 years. The theory forms the basis of many Code crack prediction equations, and the derivation of these is discussed. A.W. Beeby
