Evaluation on the Prediction Model for the Compressive Strength of Concrete mixing Blast Furnace Slag Powder at early-aged by Maturity Method

적산온도에 의한 고로슬래그 미분말 혼입 콘크리트의 초기재령 압축강도의 예측 모델식 적용성 평가

The exiting studies on the strength prediction by maturity method is mainly focused on concrete using OPC, meanwhile the study on the concrete mixing blast furnace slag powder (BFSP) is insufficient. The purpose of this study is to investigate the relationships between compressive strength and equivalent age by existing Maturity functions, i.e., Nurse-saul function Arrhenius function. This study also compared and examined the strength prediction of concrete mixing BGSP using ACI model and Logistic Curve prediction equation. Therefore, it is intended that fundamental data are presented for quality management and process management of concrete mixing BFSP.
