Concrete Performance in Crystal Dam, Colorado: 1-Year Core Report
Crystal Dam is located in the Black Canyon of the Gunnison River, about 40 km (25 mi) west of the city of Gunnison in Montrose County, Colorado. The principal construction features include the mass concrete dam with an overflow spillway, intake and outlet structures, and a power plant. The double-curvature, thin-arch concrete dam has a structural height of 98 m (323 ft) and a crest length of 194 m (635 ft). The dam contains 112 390 cubic meters (147 000 cubic yards) of mass concrete. As part of the Bureau of Reclamation's ongoing program to monitor and evaluate the strength and elastic properties of mass concrete in major dams, cores were extracted from Crystal Dam for testing at three different ages: approximately 70 days, 6 months, and 1 year. This report presents the results of laboratory tests on these cores. For further monitoring and evaluation of the properties of the concrete, additional cores will probably be extracted from the dam through 20 years' age.
