Due to the change in the occupation of hydrographic basins, more solid materials can be released to the water courses, which increases the susceptibility to erosion by impact of hydraulic surfaces. In areas where there is an intense carrying of solid material by water, the concept of the structure must take into account the possibility of erosion being severe. It is essential, then, to determine the composition of the concrete used in new projects or in the repair of existing problems. Tests must be performed in an equipment that simulates the erosive phenomenon, in a realistic perspective. This project consists of an experimental research, developing and optimizing an equipment that simulates the erosion of concrete and mortar by water-solid mixture.
