초록

This study aims to examine the practical feasibility of self-healing pellets that were manufactured using cementitious materials to repair mortar cracks. Two types of the crack self-healing pellets were prepared: surface hardening coating treatments and double coating encapsulation treatments. The crack healing efficiency of the pellets was assessed by the water-permeability tests for mortars with artificially induced cracks. The compressive strength development of mortars including the self-healing pellets treated with surface hardening coating was comparable to control mortars not inclusive of the pellets. For the crack closure against the nominal width of 0.3 mm at an age of 56 days, the mortar specimens with pellets treated with the surface hardening coating exhibited a 91% healing rate, whereas the pellets treated with the double coating encapsulation displayed a healing rate that did not exceed 75%. Overall, the self-healing pellets with surface hardening coating treatments were promising in repairing shrinkage or thermal cracks developed in mortars.
