In order to reduce the cost of conventional Strain Hardening Cementitious Composite (SHCC) and then increase its field application, a ductile SHCC material is developed using domestic PVA fibers as well as other local ingredients, including cement, fly ash, silica fume and sand. To better understand its mechanical behavior, four-point bending test, uniaxial compression and tension test were carried out to characterize the bending, compressive and tensile behavior of the newly developed composites. The test results reveal that the newly developed SHCC using local ingredients exhibits deflection hardening accompanied with multiple cracks in flexure. In addition, complete stress-strain curves in uniaxial compression and tension were obtained. Based on the test results, the compressive parameters, including the elastic modulus, the strain at the peak stress and the Poisson's ratio, were evaluated.
