Abrasion erosion damages are created by the impinging of waterborne silt, sand and other debris on the concrete surface during operation of hydraulic structures. Failure mechanism of the wear occurs in three stages. In initial stage water molecules permeate on the surface and the crusting occurs. In the second phase the impact of suspended solids in the water, cause cracks in the concrete surface. In the third stage, the wear occurs.
Does anyone have complete information in this regard,
Or an article or a book to introduce.
Many thanks in advance for your answers.

it is the most cutting and microcutting by debris carried by the water. the intensity of the phenomenon depends on the angle and velocity of water particles
Thank you so much
what do you mean by water particles ? (debris and waterborne, water molecules or water flow)
Im sorry, my english is not the best. This sediment particles cause the cutting cement paste. Abrasion wear of concrete depends on the diameter of the particles and the velocity of the water, which it transports
Most serious mechanism of concrete erosion in contact with water is cavitation. Design of water constructions has to avoid cavitation.

Do you have any paper about wear mechanism or wear stages ?
