초록

본 연구에서는 모르타르와 직접 혼합 가능한 결정성장형 무기재료 활용 고상 캡슐을 제조하였으며, 결정성장형 무기재료 조성비에 따라 3수준의 고상 캡슐을 제조하였다. 제조된 고상 캡슐은 시멘트 질량에 3% 혼합하여 모르타르의 품질 및 균열 치유 특성을 평가하였다. 고상 캡슐을 혼합한 모르타르의 테이블 플로우 및 공기량 평가결과 고상 캡슐의 혼합에 관계없이 테이블 플로우 및 공기량에 미치는 영향은 없는 것으로 나타났다. 고상 캡슐을 혼합한 모르타르의 water flow test 및 crack closing test에 따른 균열 치유특성 평가결과 초기 투수량이 감소하는 결과가 나타났으며, 시간 경과에 따라 반응생성물 발생하여 균열이 치유되는 것을 확인할 수 있었다.

In this study, solid capsules using crystal growth-type inorganic materials that can be directly mixed with mortar were prepared. Thus, three levels of solid capsules were prepared. The prepared solid capsule was mixed with 3% of the cement mass, was evaluated quality and crack healing properties of the mortar. As a test results of the table flow and air content of the mortar mixed with the solid capsules showed that mix of the solid capsules was no effect on the table flow and air volume. As a test result of the crack healing properties of the mortar mixed with the solid capsule according to water flow test and crack closing test, the initial flow rate was decreased, it was confirmed that the reaction product occurred over time and the cracks were healed.
