Review of Erosion Causes and Important Factors on the Abrasion Resistance of Concrete

The long-term impact of waterborne solids may lead to the destruction of significant amounts of concrete in hydraulic structures, including spillways, dams, and culverts. Hydraulic structures' durability heavily depends on the concrete surface's resistance to mechanical erosion. Abrasion of the surface brought about by the continuous loss of material due to the impact of solid particles suspended in water is known as hydro-abrasion. This kind of gradual degradation of the concrete surfaces is noticeable in almost all hydraulic structures, although to varying degrees. Hydro-abrasive concrete wearing often leads to a decrease in the lifespan of the hydrotechnical facility. Consequently, the facility needs repairs, causing it to be non-functional during the repair time and increasing expenses. This paper aims to provide a comprehensive overview of concrete abrasion and its mechanisms, as well as briefly discuss the elements that significantly affect the rate of abrasive erosion. The research also found that to enhance the abrasion resistance, concrete properties needed to be modified, along with an increase in compressive strength
