dc.description.abstract본 연구에서는 알루민산칼슘 시멘트(CAC)의 철근 부식 저항성에 관한 것으로서 철근 부식의 위험성을 예측하기 위하여 철근 부식거동, 염화물 고정화/완충 및 염화물 침투성을 평가하였다. 알루민산칼슘 시멘트 모르타르는 양생 온도와 시멘트의 종류에 관계없이 철근에 부식이 발생하지 않은 반면, 보통포틀랜드시멘트(OPC)는 철근 표면에 심각한 부식이 발생하였다. CAC의 염화물 결합력은 OPC에 비하여 낮은 것으로 나타났지만, pH 감소에 대한 완충 능력은 CAC 페이스트가 훨씬 더 높은 것으로 나타났다. 또한 알루민산칼슘 시멘트를 사용한 시편의 모든 깊이에서 염화물 유입이 감소함으로서 철근 부식의 위험성이 낮아지는 것으로 나타났다.-
dc.description.abstractThe present study concerns the resistance of calcium aluminate cement (CAC) to steel corrosion. The corrosion behavior of steel, chloride binding/buffering and chloride transport were evaluated in order to predict the risk of steel corrosion. The CAC mortar exhibited no corrosion on steel, irrespective of the curing temperature and CAC types, whereas ordinary Portland cement (OPC) showed a severe corrosion on the steel surface. The chloride binding capacity of CAC found to be was lower than that of OPC, yet buffering capacity against pH decrease was found to be significantly higher in the CAC paste. Furthermore, chloride ingress at all depths was found to be reduced in CAC, thereby reducing the risk of corrosion.-
