본 연구에서는 시멘트 복합체에 시멘트계 재료로 구성된 자기치유 캡슐을 적용하여 콘크리트 구조물의 자기치유 성능을 향상시키기 위한 연구의 일환으로 PCC(Powder Compacted Capsule) 크기 및 혼입율에 따른 모르타르의 공학적 특성을 비교ㆍ분석하였다. 이를 위해 PCC 크기 및 혼입율에 따른 모르타르의 유동성, 압축강도, 하중재부하 시험, 탄산화, 초음파속도, 투수 특성 등을 측정하였다. 측정 결과, PCC의 혼입율이 증가할수록 유동성과 압축강도가 증가하였으며, 치유특성 검토를 위해 진행한 하중재부하 시험의 경우 03PC 배합에서 PCC 혼입율이 증가할수록 치유율이 증가하였다. 정수위투수 시험의 경우 PCC를 사용할 경우 유출수량 감소율이 Plain 배합에 비해 최대 35 % 높은것으로 나타났으며, 크기 0.3~0.6 mm의 PCC를 15 % 혼입할 시 모르타르의 균열 치유율 향상에 효과적인 것으로 나타났다.

Abstract ▼ AI-Helper

In this study, as part of a study to improve the self-healing performance of concrete structures by applying self-healing capsules made of cementitious materials to cement composite materials, the engineering characteristics of mortars according to PCC(Powder Compacted Capsule) size and mixing ratio were compared and analyzed. For this, fluidity, compressive strength, reload test, carbonation, ultrasonic velocity, and water permeability characteristics were measured according to PCC size and mixing ratio of mortar. As a result of the measurement, the fluidity and compressive strength increased as the mixing ratio of PCC increased, and in the case of the load reload test, the healing ratio increased as the mixing ratio of PCC increased in the 03PC formulation. In the case of water permeability test, it was found that when PCC was used, the reduction ratio of water flow was up to 35 % higher than that of Plain, and when PCC with a size of 0.3 to 0.6 mm was mixed with 15 %, it was found to be effective in improving the crack healing ratio of the mortar.
