Abstract: Even in case of conventional concrete, cracks width of about 0.1 mm or smaller is relatively safe due to self-healing autogenously achieved by immersing in moisture. In this self-healing phenomenon, fiber reinforced cementitious composites (FRCC) that enable to keep the crack width smaller can be greatly effective. In order to investigate the self-healing capability of FRCC, some experiments were carried out that focused on the recovery of mechanical properties and chemical precipitation on the crack surface. Kinds and length of the contained fibers were adopted as the experimental parameters. The self-healing capability of the specimens was investigated by means of microscope observation and water permeability test. As a result, it was shown that different types of fibers lead a different performance of the self-healing effect.
