Mechanical Performance Evaluation of Fiber Reinforced Mortar Incorporating Self-healing Agents
This study aims at the characterization of self-healing capacity of fiber-reinforced mortar.The employed mortar consisting of synthetic fibers of polyvinyl alcohol (PVA) type and two different types of self-healing materials were used.An experimental work was carried out to investigate the role of fibers on self-healing efficiency of fiber reinforced mortar specimens through three-point bending test and microscopic observation.Specimens were pre-cracked to the level of the crack width of 200μm at 7 days of curing and then, placed in water for 28, 56-days.After specified exposure duration, specimens were microscopically observed again to check the crack healing and re-loaded up to final failure.Results were taken in terms of recovery of strength and stiffness.It was found from test results that the healing efficieney in terms of mechanical performance of fiber-reinforced mortar was improved, due to the use of self-healing materials and fiber bridging behavior.
