This paper reports on a comprehensive study on the mechanical properties of expansive fiber-reinforced strain-hardening cement composite (SHCC) strengths(30 and 70MPa) materials containing various replacement levels (0 and 10%) of an expansive admixture and 1.5% polyethylene (PE) fibers volume fraction. A number of experimental tests were conducted to investigate compressive strength, flexural strength, and direct tension behavior. Test results show that as expected, the different replacement ratio of an expansive admixture have an important effect on the evolution of the Materials of SHCC with a rich mixture. Test results show that as expected, the different replacement levels of an expansive admixture have an important effect on the evolution of the free shrinkage of SHCC with a rich mixture. As an alternative under expansive admixture evaluated the performance of SHCC expansive admixture alternative than if the substitution did not substantially improve performance, the expansion of the alternative material PE30 than PE70 tend to represent better. This implies that the replacement of 10% expansive admixture for PE30 is excellent
