Construction of concrete structures that located in extreme environments are such as coastal areas will result in decreased strength or even the damage of the structures. As well know, chloride contained in sea water is responsible for strength reduction or structure failed were hence maintenance and repairs on concrete structure urgently needed. One popular method of structural improvements which under investigation is to use the material Glass Fiber Reinforced Polymer which has one of the advantages such as corrosion resistance. This research will be conducted experimental studies to investigate the flexural behavior of reinforced concrete beams with reinforcement GFRP-Sheet immersed in sea water using immersion time of 1, 3, 6 and 12 months. Test specimen consists of 11 pieces of reinforced beams with dimensions (15x20x330) cm that had been reinforced with GFRPSheet in the area of bending. The test specimen tested by providing a static load until it reaches the power limit, to record data during the test strain gauge mounted on the surface of the specimen and the GFRP-Sheet to collect the strain value. The result of analysis indicates the bonding capacity of GFRP Sheet decreases about 11.04% after immersed for 12 months in sea water.
