Concrete Performance in Yellowtail Dam, Montana 10-Year Core Report
Ten-inch (25-cm) diameter concrete cores were extracted from mass concrete in Yellowtail Dam, Montana, 6 months, 1 year, 5 years, and 10 years after the concrete was placed. These cores were tested to determine physical properties of the concrete and to monitor changes in such properties with age. Test results indicate a good quality, well consolidated, durable concrete. Average compressive strength at 10 years' age was 5,010 lb/sq. inch (34.5 MPa) for typical interior concrete and 5,000 1b/ sq. inch (34,.5 MPa) for exterior concrete. Average moduli of elasticity at 10 years' age of interior and exterior concretes were 6.35 x 106 Th/in2 and 6.29 x 10 lb/ sq. inch (4.38 x 10 MPa and 4.34 x 10 MPa) respectively. Average tensile strengths of the interior and exterior concretes at 10 years' age were 2.56 lb/ sq. inch and 268 1b/ sq. inch (1.76 MPa and 1.85 MPa) respectively.
