초록
Concrete structures are susceptible to cracking which exacerbate the durability of these structures. For this purpose, selfhealingphenomena has been introduced in the past few decades. In order to apply the granulated healing material (Granule)with PVA film coating in the concrete, cracks, which were generated by drying shrinkage, were introduced to plate-shapedconcrete specimens incorporating Granule with PVA film coating. Subsequently, healing efficiency was verified by test aboutcrack, which was subjected to the water supply. As a result, it is verified that the method by using water-soluble PVA filmcoating for maintaining self-healing efficiency of the granulated healing material will be the original approach for sustainableconcrete with self-healing capability compared with the previous method.
