초록

철근 콘크리트 구조물의 염해 내구수명 산정을 위해서는 비래염분량 평가가 필수적이다. 현재까지 국내에서도 국외에서 개발된 포집기를 주로 사용해 왔으나 포집기 자체의 결함으로 포집 정확도에 문제가 있다는 지적이 일어왔었다. 본 연구 결과 기존의 포집기는 후풍의 영향을 배제할 수 없어 실제 포집기를 통과하면서 거즈에 부착된 비래염분은 후풍의 영향에 의해 이탈되어 포집량이 낮게 평가됨과 동시에 방향성, 즉 남쪽에서 불어오는 비래염분도 북향하고 있는 포집기에 포집되어 방향에 대한 구분이 없어지는 현상을 해석적, 실험적으로 규명하고, 문제해결형 개량형 포집기를 개발하였다. 또 해안지역에서 실측에 사용하여 높이별 비래염분량 측정과 동시에 포집기의 성능검증을 실시하였다.

Evaluation of the amount of chloride ion coming from the sea is very important in assessing the life expectancy of Reinforced Concrete structures. Developed in Japan, the incoming salt collector has been used to this day. Unfortunately, the incoming salt collector has had a bad reputation, which is caused by backward wind. Backward wind causes a reduction of the amount of salt collected in collector's gauze. The collector was developed to eliminate the effect of backward wind. Simulation test in the laboratory and site measurement were performed to determine the amount of incoming salt according to the height. The performance was verified through analytic and experimental methods.
