| Abstract: | Roller Compacted Concrete (RCC) construction techniques are used to raise existing dams and to build new dams. A particular and assumed advantage of the RCC technique is improved homogeneity in concrete condition throughout the dam. An opportunity to evaluate this on a large RCC dam was made available by the U.S. Army Corps of Engineers at Portugues Dam. Through the application of a relatively new testing technique, estimates of a wave-speed-based Performance Indicator (PI) of the dam were obtained. The PI relates wave speeds associated with shear wave propagation in the dam to compression wave speeds for healthy concrete. Values ranging from 1.7-2.2 for Portugues Dam compare favorably to a value of 1.6 for nominal concrete. |
