Abstract

This research deals with the properties of fresh and hardened high-performance concrete(HPC) incorporating high-reactivity metakaolin(HRM). The properties of fresh and hardened state concrete were investigated included air content, slump flow, setting time, heat of hydration, compressive strength, resistance to chloride-ion penetration, abrasion and repeated freezing and thawing. The properties of the HRM concrete were also compared with those of the portland cement concrete and silica fume(SF) concrete. The laboratory test results indicate that HRM material can be used as a supplementary cementitious material to produce high-performance concrete.

본 연구는 고반응성 메타카올린(HRM)을 혼입한 고성능 콘크리트(HPC)의 굳지 않은 콘크리트와 경화된 콘크리트의 특성을 평가하기 위해 수행되었다. 굳지 않은 콘크리트에 대해서는 공기량과 슬럼프 플로우, 응결시간 및 수화열 측정 시험을 실시하였다. 경화된 콘크리트에 대해서는 압축강도 및 염화물 투수시험, 마모저항성, 동결ㆍ응해 저항성 시험을 하였다. HRM 콘크리트의 특성은 또한 보통 포틀랜드 시멘트 콘크리트와 실리카 흄 콘크리트와 비교하여 나타내었다. 실험 결과 HRM 재료가 고성능 콘크리트를 생산하기 위한 시멘트 대체 재료로서 사용할 수 있음을 보여주었다.
