Abstract

In this article, we would like to investigate a durability characterization of cement mortar with inert filler, which is ground calcium carbonate(GCC). The kinds of techniques to evaluate cement mortar are chloride ion ingress, carbonation and sulfate attack. For the experimental result of the resistance of chloride ion ingress, carbonation and sulfate attack, as the addition of GCC makes decreasing the permeability by micro-filler effect, the specimens of $5{\sim}15%$ ratio of replacement are superior to the GCC0 mortar specimen with respect to durability of cement matrix in this scope.

본 연구에서는 중질탄산칼슘을 콘크리트용 혼화재로 활용하기 위한 연구의 일환으로 중질탄산칼슘을 시멘트 중량의 0, 5, 10 및 15%의 4단계로 혼합한 시멘트 경화체를 제조한 후 시멘트 경화체의 염소이온 침투저항성, 탄산화 및 황산염침식 저항성 등과 같은 내구 특성을 평가하였다. 실험결과 본 연구 범위내에서 혼합율에 관계없이 중질탄산칼슘을 혼합한 시멘트 경화체의 경우 염소이온 침투저항성, 탄산화 저항성, 황산염침식 저항성은 중질탄산칼슘의 충전효과에 의하여 중질탄산칼슘을 혼합하지 않은 시멘트 경화체에 비하여 저항성이 다소 향상된 것으로 나타났다.
