COMPARATIVE ADIABATIC TEMPERATURE-RISE TESTS OF MASS CONCRETE.

Abstract

Two identical adiabatic calorimeters designed to accommodate 30- by 60-in. cylindrical concrete specimens were placed in operation at the U. S. Army Engineer Waterways Experiment Station (WES) in 1961. They are used to determine the temperature rise in concrete that is caused by the exothermic chemical reactions of the cementitious materials. After the calorimeters were used for several months, the test procedure was revised. This revised procedure improved the accuracy of test results. Comparative tests were conducted at the University of California, where a similar calorimeter, identical concrete mixture, and the same test procedure were used. The temperature rise at 28 days was within 0.54 F of that of WES specimens. It is concluded, therefore, that the current test procedure is satisfactory. The test procedure, CRD-C 38-66, is included as Appendix A, and the University of California report of tests is included as Appendix B. (Author)
