Abstract

In this study, self-healing hybrid capsules were prepared by mixing self-healing solid capsules and self-healing microcapsules using inorganic materials as core materials. Self-healing hybrid capsules were mixed with 3 % according to the composition ratio of 3:7, 5:5, and 7:3 based on the mass of the cement to prepare a self-healing cement composite material. The healing properties of crack self-healing hybrid capsules were evaluated through hydrostatic water permeability test and surface crack monitoring. It was found that the self-healing hybrid capsules prepared by mixing the composition ratio of the self-healing solid capsules and the self-healing microcapsules at 7:3 has a great effect on improving the crack self-healing performance.

본 연구에서는 무기재료를 코어재료로 사용한 자기치유 고상캡슐 및 자기치유 마이크로캡슐을 혼합하여 자기치유 하이브리드 캡슐을 제조하였다. 자기치유 하이브리드캡슐을 시멘트 질량 기준으로 3:7, 5:5 및 7:3의 조성비에 따라 3 % 혼합하여 자기치유 시멘트 복합재료 배합을 진행하였으며, 정수위 투수시험 및 표면균열 모니터링을 통해 균열 자기치유 하이브리드캡슐의 치유 특성을 평가하였다. 실험 결과, 자기치유 고상캡슐 및 자기치유 마이크로캡슐의 조성비가 7:3으로 제조된 자기치유 하이브리드 캡슐을 혼합함에 따라 균열 자기치유 성능을 향상시키는 효과가 큰 것으로 나타났다.
