Besides many authoritative treatises and text books dealing with the subject of reinforced concrete, individual research, committee-reports, and the standards of the leading engineering societies have all contributed to improve our methods of design and construction. Those standards of the American Society for Testing Materials which particularly apply to the design and specification of reinforced-concrete buildings have been included in full. The following list of classified references, abstracted from the bibliography prepared by Professor Duff A. Abrams of the Lewis Institute, contains the results in this field of the more important research work of the last twenty years. BOND Variation of Bond with Compressive Strength, by M. O.
