| Abstract: | Considering that the surfaces of the concrete substrates are always in moist state in hydropower construction, the bonding properties of spraying polyurea elastomer (SPUA) coatings on the moist concrete substrate surfaces were introduced. The results showed that the bonding strength of SK type surface treating agent on moist concrete substrate can reach over 5.0MPa and the bonding strength of SPUA coatings on the moist concrete substrate surfaces treated with the surface treating agent can reach over 2.5MPa. |
