초록
본 연구에서는 산업부산물로서 재활용율이 낮은 바텀애쉬와 혼화재를 이용하는 에코개념의 터널 보수용 초속경 그라우트 모르타르 개발을 목적으로 실시공 환경조건의 온도하에서 초속경 그라우트 모르타르의 수밀성 및 내구특성에 대하여 검토하였다. 수밀성으로 투수량 및 물흡수계수는 석탄회를 이용하는 시리즈 II의 경우가 증가하는 것으로 나타났으며, 온도조건별로는
In this study, in order to develop ultra rapid hardening mortar(URHM) for tunnel repairs using bottom ash of low recycle ratio and Admixture as Eco concept, watertightness and durability properties of URHM on temperature condition of construction field were performed. Test result, seepage quantity and water absorption coefficient regarding watertightness of URHM were as in the following : series II > series I. Seepage quantity for the standard condition were smaller than low temperatures. all specimens were satisfied below 20g as standards of seepage quantity on KS F 4042. Because of the decrease of unit cement content by to replacement of blast furnace slag, the neutrlization resistance for durability properties was reduced. The result of alkali resistance and acide resistance, compressive strengths for specimens soaked in calcium hydroxide solution of seriesI were lower than compressive strengths for specimens not soaked. On the other hand, the case of series II show that the deterioration of compressive strengths for specimens was not almost showed. Compressive strengths of specimens soaked were similar with specimens not soaked except series II-C in
