This paper reports on a comprehensive study on the mechanical properties of expansive fiber-reinforced strain-hardening cement composite (SHCC) materials containing various replacement levels (0, 8, 10, 12 and 14%) of two type of CSA expansive admixture and 1.5% polyethylene (PE) fibers volume fraction. A number of experimental tests were conducted to investigate shrinkage,
compressive strength, flexural strength, and direct tension behavior. 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. Also, two types of CSA expansive admixture show different appearance in replacement levels. In Type-1, an increase in replacement levels of expansive admixture from 12% to 14% does not lead to a significant improvement for mechanical properties; this implies that the replacement of 10% expansive admixture is sufficient. Simultaneously Type-2 shows slight improvement in more than 10%
of replacement level and It implies 8% expansive admixture is sufficient.
