Abstract

High performance concrete containing silica fume for use in bridge deck overlay emerged as a viable type of bridge deck overlay that economic advantage in construction. They have gained acceptance in Europe, America and Canada in a relatively short time due to their low cost. In this study, high-performance concretes containing silica fume were tested and evaluated in the laboratory to assess their applicability for use in bridge deck overlay. It was conducted with experiments of mechanical and durability characteristics in compressive strength, flexural strength, chloride permeability, abrasion resistance, repeated freezing and thawing cycles and deicing salt scaling resistance. Laboratory test result describe that high-performance concrete containing silica fume for bridge deck overlay application shows most outstanding capacity.

교량 교면에 적용되는 실리카퓸을 혼합한 고성능 콘크리트는 경제성이 향상된 교면 포장 방법이다. 실리카퓸 콘크리트는 기존의 LMC와 비교하여 경제성 향상으로 미국, 유럽, 캐나다 지역에서 비교적 짧은 기간에 널리 사용하고 있다. 본 연구에서는 실리카퓸을 혼합한 고성능 콘크리트의 교면 포장에 대한 적용성을 알아보기 위하여 실내 실험을 실시하였다. 실내 실험은 물리, 역학적 및 내구성능을 평가하였는데 실험 결과 실리카퓸을 혼합한 고성능 콘크리트는 우수한 성능을 발휘하였다.
