Abstract
본 연구에서는 고로슬래그 미분말 혼입율별 활성화에너지(Ea)를 산정하고, 이를 이용하여 등가재령 산정 후 Carino model을 이용해 고로슬래그 미분말 혼입율을 고려한 압축강도 예측을 실시하였다. W/B 60%에서 BFS 혼입율 0%, 10%, 30%, 50%에서 Ea 가 33.475 kJ/mol, 37.325 kJ/mol, 41.958 kJ/mol 및 45.541 kJ/mol로 산정되었다. 그 결과 양호한 압축강도 예측을 하였다.
The purpose of this study is to predict the compressive strength of concrete with BFS by calculating the apparent activation energy (Ea) for each BFS replacement ratio, applying this activation energy to the equivalent age model, and then using the Carino model. For BFS replacement ratios of 0%, 10%, 30%, and 50%, Eais calculated as 33.475 kJ/mol, 37.325 kJ/mol, 41.958 kJ/mol and 45.541 kJ/mol respectively. As result of experiments, the compressive strength of concrete with BFS is predicted.
