The United States Bureau of Reclamation, 1992
This manual, published primarily for use by the Bureau's construction engineers and inspectors, supplies engineering data and outlines methods and procedures to be followed in administering construction specifications. Although issued primarily for Bureau of Reclamation staff use, the manual has received widespread acceptance throughout the United States and in many foreign countries.
The Ninth Edition of the Concrete Manual, unlike previous editions, has two parts. Part 1 contains the text on concrete technology. This volume, Part 2, is a compilation of concrete test procedures currently used by the Bureau of Reclamation. Part 2 includes many procedures that were not in the Eighth Edition Appendix. A few procedures in the Eighth Edition are outdated; consequently, they were not reproduced in this edition. Some of the previous procedures were combined into a single procedure in this edition; other procedures were modified. While some of the new procedures are based upon previous procedures, attempt is not made to cross reference the procedures in Part 2 (9th ed.) with those in the Eighth Edition (app.).
These test procedures are frequently referenced in Reclamation construction specifications and thereby become a part of a construction contract. If the specifications reference test procedures in Concrete Manual, Eighth Edition, those procedures in the Eighth Edition become part of the contract and no attempt should be made to use an updated version in the Ninth Edition for that particular contract. If the specifications reference test procedures in Part 2, Ninth Edition, those procedures become a part of the contract; procedures from previous editions do not apply. Where specifications requirements are at variance with referenced test procedures, the specifications take precedence.
