Abstract

The degradation of the concrete due to deterioration factors, such as corrosion of steel bars, cracks and structural strength of reinforced concrete structures, is a social problem. Especially, concrete structures constructed in seawater, underground water, waste water treatment facilities and sewerage are subject to chemical attack by acid and sulphate. Therefore, this study was conducted to compare sulfated glass and fine aggregate of slag using waste glass fine powder and meta kaolin. The results showed that the slag fine aggregate showed better sulfate resistance than the river sand, and the fine powder of waste glass showed the best performance at 3 % displacement.

콘크리트는 열화요인에 의해 철근콘크리트구조물의 철근부식, 균열발생 및 구조내력저하 등 성능저하현상이 사회적 문제점으로 대두되고 있다. 특히 해수, 지하수 또는 오 폐수처리시설 및 하수도 등에 건설되는 콘크리트 구조물은 산 및 황산염에 의한 화학적 침식을 받는 경우 내구성이 크게 저하되어 대책이 필요하다. 따라서 본 연구는 폐유리 미분말과 메타카올린을 사용하여 강모래와 슬래그 잔골재를 비교하여 내황산염성 실험을 진행하였다. 평가 결과 강모래보다 슬래그 잔골재가 내황산염성이 우수하였으며, 폐유리 미분말은 3 % 치환에서 가장 우수한 성능을 발현하였다.
