At the request of the United States Atomic Energy Commision, a basic research program to develop and improve the technology of prestressed reactor vessels was formualted and initiated by the Oak Ridge National Laboratory, which is operated by the Union Carbide Corporation. As a part of this program, and extensive study of the time-dependent deformation of concrete specimens subjected to various stress conditions and elevated temperatures was begun at the University of Texas at Austin. This paper discusses the experimental aspects of this study and includes the preliminary investigations, preparation of specimens, and instrumentation as well as the testing procedure (References 3 and 4). Data analysis and results of the study are presented in Reference 1, 2, 4, 5, and 6.
