This paper presents experimental results for durability performance of GFRP composite exposed to the alkali solution. Additives used in this study were PVA, kaolin clay, and alumina powder. Temperature was 80℃ for the first test. The condition of second test is the 20℃ alkali and tap water solution for the cases of no additive and PVA. Specimens were immerged up to 30 days and tested for tensile strength for each immersion time. The results indicate that it is important to fill the inner space of GFRP composite densely to avoid the decrease of tensile strength. In this study, PVA showed better performance than other additives.
