Abstract

In this study, to improve the durability of concrete structures constructing newly or renewal, the physical properties and durability of concrete with binders combining high-early-strength Portland cement with different mineral admixtures were tested, and their applicability to prestressed concrete structures was examined. The results showed that their application to actual prestressed concrete structures was possible, al- though the strength development and drying shrinkage strain varied by the type of mineral admixtures used. The results of durability test also indicated that it was possible to improve the durability of concrete by select- ing appropriate admixtures.
