[1191] STUDY ON STRAIN-HARDENING CEMENTITIOUS COMPOSITES WITH HIGH VOLUME SLAG: UNIAXIAL TENSILE PERFORMANCE AND CHLORIDE MIGRATION
Keywords:SHCC、 blast furnace slag、 uniaxial tension、 ductility、 chloride migration
This study evaluated strain-hardening cementitious composites (SHCC) with high slag volume to compare with normal fly ash-based one by testing compressive strength, uniaxial tensile performance and non-steady chloride migration. Results indicated that slag-based SHCC generally exhibited higher compressive and tensile strength as well as better chloride resistance than fly ash-based one. However, ultimate tensile strains tended to decrease with age and eventually obtained lower values than fly ash.
