염해환경에 노출된 콘크리트 실험체의 역학적 특성 = The Characteristics of Strength of Concrete Specimens under Tidal Environment

다국어 초록 (Multilingual Abstract)

The building that supply tidal and splash zone was constructed near Seamangeum Gate Bridge. The specimens were exposed on the tidal and splash zone, totally about 650(Fig. 1) that will be tested for maintenance of gate bridge. The characteristics of strength, salt penetration profile, field application of surface repair material and section recover material will be acquired by periodical test. The program was developed to obtain optimal maintenance strategy of gate bridge as a marine concrete structure and to deposit experimental data, lab. test result, field test result, on its D/B. On this paper, we hope to introduce one year exposure data as compressive strength, the modulus of elasticity, the modulus of dynamic elasticity, field adoption of repair and recover materials. As briefly speaking the results, possion's ratio, elasticity, strength was general, but the recover materials have some problems. There was crack between concrete and recover material and delamination figures.
