This study aims to improve the self-healing performance of concrete structures by using self-healing capsules composed of amorphous metalfibers and cement-based materials together to mitigate the quality degradation problem of concrete caused by capsules. The amorphous metalfiber reinforcement according to the PCC mixing ratio and the engineering characteristics of mortar were compared and analyzed. To thisend, the mortar's fluidity, compressive strength, tensile strength, carbonation, ultrasonic velocity, and chloride ion permeation resistanceaccording to the PCC mixing ratio were measured. As a result of the measurement, the fluidity decreased as the mixing ratio of PCCincreased, and the compressive strength showed a tendency to decrease as the mixing ratio of PCC increased regardless of the mixing ratioof amorphous metal fibers. In the case of tensile strength, the mixture using amorphous metal fiber and PCC showed a maximum increase of46.9% compared to the plain mixture. In the case of the carbonation depth, the lowest carbonation depth was shown in the AF-PCC15mixture mixed with PCC 15% and amorphous metal fibers.
