Abstract:

Pertinent physical characteristics, particularly ultimate tensile strain capacity, of one simulated interior and one exterior concrete mixture containing the coarse aggregate under consideration for use in Clarence Cannon Dam were determined for input to a finite-element computer code for prediction of temperature rise in mass concrete. Results will provide a basis for the establishment of some of the temperature and construction control plans aimed toward minimizing thermal cracking. Generally, the ultimate strain capacity for Clarence Cannon Dam is more closely related to that of Libby Dam which had a cracking problem than to that of Dworshak Dam which had no cracking problem. This is particularly true of the increase in strain capacity, slow versus rapid loading, where the Cannon Dam increase averaged 1.4 times as compared in increases of 1.2 to 2.1 times for Libby and Dworshak Dams, respectively.
