This paper investigates The purpose of this research was to investigate the effects of expansive admixture on the tension stiffening performance and cracking process of SHCC with polyethylene(PE) fiber. Testing was carried out on four axially loaded tension tie specimens. Each specimen had a square cross-section dimension 100 × 100mm of and length of 1200mm. As a result, using an expansion admixture can improve a prestress and reduce an initial shrinkage crack.
