A Study on Strength Development Constant of Concrete for Performance Based Design

The recent worldwide trend in construction industry tends to put emphasis on the performance based design which focuses on the suggestion of the performance of final products rather than method and procedures. A proper model should be employed when predicting the concrete strength, which reflects the material age, in order to verify the function of concrete structures and their materials. Accordingly, this paper proposes the concrete strength development constant () reflecting the characteristics of domestic materials and then evaluates its suitability.
