Shrinkage behavior influence of strain‐hardening cementitious composites.

This paper presents an experimental investigation into the shrinkage behavior of strain‐hardening cementitious composite (SHCC), which focuses on the influences of varied ingredients in mix proportions and curing condition. The experimental results confirm that the shrinkage strains of SHCC are obviously influenced by the investigated ingredients of SHCC, in which expansion agent can induce expansion strain for nominally reducing the shrinkage strains of SHCC, the shrinkage strains of SHCC's matrix are decreased with increasing fiber volume content and water‐to‐binder ratio, whereas those are increased with increasing silica‐fume‐to‐binder ratio. Moreover, the curing condition has significant influence for the shrinkage behavior of SHCC, and water curing can significantly reduce the shrinkage strains. This work provides experimental foundations for shrinkage behavior of SHCC. [ABSTRACT FROM AUTHOR]
