초록

This study developed a biodegradable coating approach for crack self-healing pellets produced using cementitious materials, bacteria to prevent physical damage and minimize previous reactivity with water from the pellets during the mixing phase of concrete. This study aims to examine the crack healing efficiency of biodegradable coating pellets through hydrostatic permeability tests using mortar specimens with nominal crack widths of 0.3 mm and 0.5 mm. Test results showed that the biodegradable coating pellets insignificantly affected the compressive strength gain of mortars. The crack healing rate due to the addition of these pellets was estimated to be 91-97% for crack width of 0.3 mm and 37-55% for crack width of 0.5 mm. These rates corresponded to a 10% higher efficiency when compared to that measured for non-coated pellets.
