Mnemonic Notation for Engineering Formulae. Cracking in Reinforced Concrete

THE problem with cracking in reinforced concrete is to eliminate the formation of cracks wherever possible and to distribute the cracking that does occur so that the individual cracks are not serious. F.G. Thomas

THE need for a method of estimating the strength of concrete suitable for use in the field has long been evident. The usual method of control adopted is to make cubes periodically on a run of mixer sample and send these away to a laboratory for testing in the usual manner. In a large number of cases, however, this is impracticable if only on the ground of expense, and the only guide to the quality of the concrete is that of visual inspection. J.F. Williams
