초록

본 연구에서는 매스콘크리트의 높은 수화열을 제어하기 위하여 결정핵 (C-S-H)와 지연제(포도당)를 동시 사용하여 최대 수화온도를 낮추면서, 응결지연효과를 상쇄시키는 방법이 제시되었다. 이를 위하여 시멘트 페이스트의 수화온도를 측정하고, C-S-H와 포도당의 동시 사용이 시멘트 모르타르의 응결시간 및 압축강도에 미치는 영향을 조사하였다. 실험결과에 따르면. 칼슘실리케이트 수화물과 포도당을 동시 사용할 경우 최대 수화온도를 저감하면서도 최대수화온도에 도달하는 시간을 줄일 수 있음을 확인하였다. 또한 C-S-H와 포도당의 동시 사용은 시멘트 모르타르의 28일 압축강도에는 큰 영향을 미치지 않는 것으로 나타나, 이러한 방법이 매스콘크리트의 수화열 조절에 효과적인 대안이 될 수 있음을 알 수 있었다.

In this study, a method to reduce temperature rise due to hydration in mass concrete is investigated. It is to use retarder (glucose) for reducing heat of hydration and to use calcium silicate hydrate (C-S-H) for compensating the retardation effect due to its role as a nucleation seed. For this purpose, the temperature rise of cement paste due to hydration was measured and the effect of using both C-S-H and glucose on setting and 28-day compressive strength of mortar specimens was investigated. According to the experimental results, using C-S-H and glucose caused the reduction in the maximum temperature but accelerated the time to reach the maximum temperature compared to that of retarded cement paste using glucose. In addition, using C-S-H and glucose did not show significant effect on 28-day compressive strength of mortar specimens, indicating that the method shown in this study can be a successful alternative to control maximum temperature rise in mass concrete.
