Abstract:
Three large Brazilian dams developed problems with concrete erosion from abrasion and cavitation caused by high water velocity. Different techniques were used to make the repairs, depending on the type and extent of the damage. This article describes the damage observed, its causes, the repair work conducted, and the performance of the repairs over time.
