Abstract

In this paper, to evaluate the effect of SC on the crack self-healing performance and mechanical recovery performance of cement composites, encapsulated intumescent inorganic material-based solid healing materials were prepared. SC was mixed with cement composite materials to evaluate the basic properties, permeability test, and load reload test. SC slightly improved the flow of cement composites, and the compressive strength decreased by about 10 %. Also, the flexural strength decreased by about 30 %. It was found that when SC was mixed with the cement composite material by 5 %, the crack self-healing rate of Plain was improved by about 𝜟10 %. As a result of the load reload test, it was found that the mechanical recovery rate of Plain was improved by about 𝜟20 %. In addition, as a result of analyzing the correlation between the crack self-healing rate and the mechanical recovery rate by the load reload test, it is judged that the healing area of the Plain can be increased due to SC.

본 논문에서는 SC가 시멘트 복합재료의 균열 자기치유 성능 및 역학적 회복성능에 미치는 영향을 평가하기 위하여 캡슐화된 팽창성 무기재료 기반 고상 치유재를 제조하였다. SC는 시멘트 복합재료에 혼합하여 기초특성, 투수시험, 하중 재부하 시험을 평가하였다. SC는 시멘트 복합재료의 플로우를 다소 향상되었으며, 압축강도는 약 10 % 감소하였다. 또한 휨강도의 경우 약 30 % 감소하였다. SC를 시멘트 복합재료에 5 % 혼합할 경우, Plain의 균열 자기치유율이 약 𝜟10 % 수준을 향상시키는 효과가 있는 것으로 나타났으며, 하중 재부하 실험 결과, Plain의 역학적 회복율을 약 𝜟20 % 수준을 향상시키는 것으로 나타났다. 균열 자기치유율과 하중 재부하 시험에 의한 역학적 회복율의 상관관계를 분석한 결과, SC로 인하여 Plain의 치유면적을 증대시킬 수 있는 것으로 판단된다.
