Carbonation is a representative deterioration for underground structure, which causes
additional repair for service life. This study proposes a simplified equation for optimum repair …

Among the deteriorating agents, chloride ion is reported to be one of the most harmful ions
due to its rapid diffusion and direct effect on steel corrosion. Cold joint which occurs in mass …

콘크리트는 공용기간동안 구조물 자체의 자중 및 이동 하중에 따른 응력을 받게 되며, 이러한
응력은 구조적인 거동뿐 아니라 내구적인 거동에도 영향을 준다. 대단위 콘크리트 부재의 …

대도시의 콘크리트 구조물은 탄산화에 노출되며 사용기간의 증가로 인해 내구성 저하를
나타내며 콘크리트에 발생하는 균열은 국부적인 탄산화 증가를 야기한다. 본 연구에서는 …

Steel corrosion is a very significant problem both to durability and structural safety since
reinforcement has to support loads in tensile region in RC (Reinforced Concrete) member. In …

Concrete, as a porous media, has permeability and it is considered as a major parameter for
durability evaluation. Cold joint caused by delayed placing of concrete accelerates water …

Carbonation and chloride ingress are the most relevant damaging mechanisms for steel
corrosion in reinforced concrete structures. Massive utilization of supplementary …

The priority of repair areas are chosen with the probability distribution of 0.3 mm wide crack
and carbonation induced corrosion. Data is analyzed and evaluated based on the 28 …

Several techniques for steel corrosion detection are proposed and HCP (half cell potential)
technique is widely adopted for field investigation. If concrete has cracks on surface, steel …

설계시의 결함, 사용 중의 손상, 극한 환경에 장기간 노출에 따른 열화로 인해, 콘크리트
구조물의 성능은 감소된다. 본 논문은 8 개 구역을 가진 대도시 철도 고가교에 대한 현장조사를 …
