The purpose of this study was to evaluate the performance of wet process sprayed polymer mortar for repair of concrete under combined aging conditions. For wet process sprayed polymer mortar, fly ash and slag effect were investigated with the replacement level of 10 ~ 14% of cement weight. Tests of compressive strength, chemical resistance, repeated freezing and thawing were conducted. Test results show that the wet process sprayed polymer mortar, when using fly ash and slag, were effected on the improvement of the compressive strength and durability performance.
