본 연구에서는 등가재령의 일종인 Freiesleben함수3),4)를 이용하여 양생온도별 콘크리트의 강도발현특성을 파악한 후 기존에 제안된 강도예측모델인 Logistic식과 새로운 강도예측 모델을 비교?평가함으로서 건설생산현장에서 구조체콘크리트의 품질관리 및 공정관리에 활용할 수 있는 기초적 자료를 제시하고자 한다. |

The purpose of this study is to develope the strength prediction model by Maturity Method. A maturity function is a mathematical expression to account for the combined effects of time and temperature on the strength development of a cementious mixture. The method of equivalent ages is to use Arrhenius equation which indicates the influence of curing temperature on the initial hydration ratio of cement. For the experimental factors of this study, we selected the concrete mixing of W/C ratio 45, 50, 55 and 60% and curing temperature 5, 10, 20 and 30℃. And we compare and evaluate with logistic model that is existing strength prediction model, because we have to verify adaption possibility of new strength prediction model which is proposed by maturity method. As the results, it is found that investigation of the activation energy that are used to calculate equivalent age is necessary, and new strength prediction model was proved to be more accurate in the strength prediction than logistic model in the early age. Moreover, the use of new model was more reasonable because it has low SSE and high decisive factor. |
