Communication Strength and shrinkage properties of alkali-activated slag concrete containing porous coarse aggregate

摘要

An investigation was conducted that examined theeffects of internal curing of alkali-activated slag concrete (AAS)by replacing normal weight coarse aggregate with fully saturatedblast-furnace slag coarse aggregate. The slow release of moisturefrom the porous aggregate provides ongoing internal curing ofconcrete. The study showed that, under drying conditions, thecompressive strength was improved and the drying shrinkage wassignificantly less (40% less than AAS containing normal weightcoarse aggregate).
