Acrylate resin and polyurethane were used as crack repairing agents which were filled in hollow glass fibers emibedded in cement mortar materiats. The subsequent release of repairing agent resulted in the sealing of matrix microcracks and the rebonding of damaged interfaces. The strength and healing quality of material were tested by INSTRON equipment and acoustic emission. The test results show that the microcracks are healed by repairing agent and the toughness is improved.
