인공해수 건습반복조건에 따른 콘크리트배합별 부식촉진시험법과 염화물 침투해석평가

Abstract

(Received November 30, 2013 / Revised December 19, 2013 / Accepted December 20, 2013)Cyclic wet and dry conditions in the marine environment structures corrosion is known to be the fastest rising. For that reason , accelerated corrosion test methods for the reproduction of tidal environment has been actively conducted. However, many studies have estimated threshold value for steel corrosion or concentrated in chloride penetration analysis. In this study, cyclic wet and dry conditions to reproduce the structure of the environment in accelerated corrosion and chloride penetration test analysis was performed. Corrosion was determined by the result of reinforcement corrosion monitoring based on galvanic potential measurementand half-cell potential method. Accelerated corrosion test results for each formulation was different corrosion periods, the or der OPC> FA> BS> High-strength concrete. FEM durability interpretation program DuCOM was conducted under the same conditions as in accelerated corrosion test. The experimental RCPT tests demonstrated the validity of the result.키워드 : 건습반복법, 부식촉진시험, 간만대 환경, 염화물침투해석Keywords : Cyclic wet and dry condition, Accelerated corrosion test, Chloride penetration analysis* Corresponding author E-mail: parkss87@smu.ac.kr
