Based on splitting tension test of engineered fiber reinforced cementitious composites（ECC） with different polyvinyl alcohol（PVA） fiber volume fractions and water binder ratios, the load deformation curve and splitting tensile strength were investigated. Results show that after PVA fiber volume fraction reaches 15%, the effects of fiber on strengthening and crack resistance are more obvious. PVA fibers can bear and transfer tension through the strong bridging effect, so PVA ECC specimens have obvious deformation strengthening characteristics under splitting tension. Furthermore, the peak tensile strength and peak deformation of specimens are increased and the ductility of specimens is improved significantly. When water binder ratio increases, PVA fibers are more likely to be pulled out, so the increase of PVA ECC peak deformation is obvious and specimens have obvious characteristics of plastic failure. Splitting tensile strength tested by the two different spacer methods was analyzed and the relationship between axial tensile strength and splitting tensile strength was established.
