A Method for the Estimation Of Compressive Strength of Concrete in the Field

The above report, which was drawn up in 1918 by the Science Committee of the Concrete Institute, has now been withdrawn from the list of publications of the Institution. In British Standard Specification No. 560/1934 the standard symbols to be used in structural engineering are printed on pages 25, 26 and 27. The few cases where this Institution uses symbols or abbreviations which vary from those contained in the British Standard Specification, are set out in a note at the foot of page 27 of the Specification.

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
