POLYMER IMPREGNATION REPAIRS OF CAVITATION/EROSION DAMAGE AT DWORSHAK DAM. IN: POLYMERS IN CONCRETE: THE FIRST THIRTY YEARS

Dworshak Dam is the third highest dam in the United States, containing 6.5 million cubic yards of concrete. In 1974 severe cavitation damage was found about 50 to 75 feet downstream of gate in outlet No. 1. The damage is described as massive removal of concrete and reinforcing steel. This paper describes the polymer impregnation in the repairs of the damaged concrete. The repairs included impregnation of conventional concrete, fibrous concrete as well as dry-pack patches and was performed on both vertical and horizontal surfaces. The paper summarizes the testing which demonstrated the improved resistance of the polymer impregnated concrete to cavitation and erosion damage. Modifications were made about 8 years after the polymer repairs to minimize cavitation by aeration.
