According to the deterioration of hydraulic structures and the high radiation feature in Tibet area, two different epoxy mortars for anti-abrasion protection were used. One was high viscosity epoxy mortar, and the other was CW epoxy mortar with high weather resistance. The two materials were applied to dealing with concrete defects of pier, located in Zangmu Hydropower Station. High viscosity epoxy mortar was used to repair inner defects, and the CW epoxy mortar was used as the surface layer, which was suitable in areas with the strong ultraviolet radiation under the condition of high speed water flow. After the impoundment, mortars successfully endured water erosion and high radiation of half a year .Results show that the material system and technology can well improve performances such as abrasion and durability of concrete of piers in hydraulic projects.
