IMPACT OF CARBONATION CURING ON THE SHRINKAGE BEHAVIOR AND COMPRESSIVE CREEP CHARACTERISTICS OF LOW-CARBON CONCRETE USING PORTLAND BLAST-FURNACE SLAG CEMENT TYPE C

This study investigates the impact of carbonation curing on the shrinkage and creep properties of low-carbon emission concrete using γ-2CaO·SiO2, based on Portland blast-furnace slag cement type C. Results indicate that carbonation curing with γ-2CaO·SiO2 e exhibited increased compressive strength and calcium carbonate content. Although shrinkage increases during carbonation curing, it stabilizes afterward. Furthermore, carbonation effectively reduces the creep coefficients regardless of γ-2CaO·SiO2.
