Engineered Cementitious Composites (ECC) are relatively new types of fiber reinforced cementitious materials with enhanced mechanical properties such as tensile strain hardening accompanying high tensile strain capacity. This is mainly attributed to close and multiple cracks with widths remaining under 60 µm which contributes to durability of ECC material. These properties are only achievable as a result of a micro-mechanical design that requires special ingredients that make ECC costly to be used alone, however it is possible to use ECC together with other construction materials such as steel and concrete. On the other hand, as a result of abundant binders and low water to binder ratio, ECC shrink more compared to other construction materials. In this paper, shrinkage properties including restrained shrinkage of four different ECC mixtures are determined along with the tensile creep behavior. Furthermore a new setup with the method and procedure to determine the tensile creep is given in details.
