Abstract

This study carried out to evaluate the hydration heat analysis and fundamental characteristics such as air content, slump and compressive strength for field application of low heat concrete with premixed cement. The results of experiment show that low heat concrete with premixed cement have sufficient performances on the workability and compressive strength. In addition, hydration heat analysis shows that low heat concrete with premixed cement make sure of target thermal cracking index. Therefore, it is desirable to apply the low heat concrete with premixed cement on pier foundation-column.

본 연구에서는 Premixed 혼합시멘트를 사용한 저발열 콘크리트에 대하여 기초물성 평가로 공기량, 슬럼프 및 압축강도 시험을 수행하고, 수화열 해석을 수행하여 Premixed 혼합시멘트를 사용한 콘크리트의 현장 적용성을 검토하였다. 검토 결과 Premixed 혼합시멘트를 사용한 저발열 콘크리트는 목표 작업성 및 설계기준 압축강도를 충분히 만족하였다. 또한, 수화열 해석 결과 Premixed 혼합시멘트를 사용한 저발열 콘크리트는 목표 온도균열지수를 충분히 확보할 수 있었다. 따라서, 현장 교량구조물의 교각 기초-기둥의 시공에 있어 Premixed 혼합시멘트를 사용한 저발열 콘크리트의 적용은 바람직한 것으로 판단된다.
