In order to investigate the self-healing capability in fiber reinforced cementitious composites (FRCC), mechanical properties and surface morphology of crack in FRCC were studied. Three types of FRCC specimens containing (1) polyethylene (PE) fiber, (2) steel cord (SC) fiber, and (3) hybrid composite fibers (both of PE and SC) were prepared. These specimens in which cracks were introduced by tensile stress, were retained in water for 28 days. The self-healing capability of the specimens was investigated by means of microscope observation, water permeability test, and tension test. It was found that many very fine fibers of PE bridged over the crack and self-healing products became easy to attach to a lot of PE fibers. As a result, water permeability coefficient decreased and tensile strength was improved significantly. Therefore amount of the PE fiber per volume was indicted to have a great influence on self-healing.
