Serious damage may occur to concrete hydraulic structures, such as water galleries, spillways, and stilling basins,
due to the abrasive erosion caused by the presence of solid particles in the flow. This underlines the importance of
being capable in providing characterization of the concrete from the point of view of its vulnerability to abrasive erosion,
in order to improve the design of the structure and the material selection. Nevertheless, the existing apparatus for concrete
abrasive erosion testing are either far from allowing realistic simulation of the actual environment in which this
phenomenon occurs, or show a large degree of complexity and cost. An alternative method has been developed with the
aid of Computational Fluid Dynamics (CFD). CFD was first employed to verify the effectiveness of a new laboratory
equipment. Afterwards, a parameter has been introduced which, by successful comparison against preliminary experiments,
proved suitable to quantify the effect of the fluid dynamic conditions on the concrete abrasive erosion, thereby
opening the way to CFD-based customization of the apparatus. In the future, the synergy of numerical and physical modelling
will allow developing predictive models for concrete erosion, making it possible to reliably simulate real structures.
