STRENGTH DEVELOPMENT OF SELF-COMPACTING CONCRETE INCORPORATING GROUND GRANULATED BLAST-FURNACE SLAG IN COLD REGIONS

Abstract

The purpose of this study is to reveal the strength development of self-compacting concrete incorporating ground granulated blast-furnace slag (ggbs) constructed in cold weather conditions. First of all, using mortar specimens varying the fineness of ggbs and the replacement level of ggbs, the strength development for various curing methods and curing temperatures is researched. Then the application of heat curing necessary for improving an early strength development at low temperatures is investigated. Finally, considering the change of season at construction site from winter to spring, the properties of strength recovery of self-compacting concrete incorporating ggbs caused by the rise of temperature are discussed.
