Recently, study on self-healing materials have been performed to increase the life by repairing the damage of structures themselves, which are difficult to repair or require high maintenance costs. A water permeability test has been widely used for the evaluation of self-healing performance. However...

콘크리트 구조물의 자기치유는 무엇인가? | 콘크리트 구조물의 자기치유는 외부 하중 및 환경인자에 의해 발생된 작은 손상이나 균열을 자연적으로 보수할 수 있는 능력이다. 최근 자기치유 재료에 대한 연구는 보수하기 힘들거나, 보수비용이 많이 소요되는 구조물에 대해 구조물 스스로 손상을 치유하여 사용수명을 증가시키기 위해 많이 수행되어 오고 있다(M. | |
autogenous healing은 무엇인가? | 일반적으로 보통포틀랜드 시멘트(OPC)의 경우 100㎛의 균열까지 자기치유를 할 수 있는 것으로 알려져 있다. 이러한 균열 자기치유를 시멘트 자체의 고유한 자기치유 특성으로서 autogenous healing이라 한다. Autogenous healing에 의한 자기치유 성능은 다른 self-healing 기술에 비해 그 효과가 크지 않은 것으로 알려져 있다 (H. | |
최근 콘크리트의 균열 자기치유 능력을 향상시키기 위해 활용하는 것은 무엇인가? | , 2003). 최근에는 시멘트계 혼합재료(supplementary cementitious materials, SCMs) 및 결정촉진체(crystalline admixture, CA) 그리고 팽창제와 팽윤제를 활용하여 콘크리트의 autogenous healing을 향상시키기 위한 연구가 활발하게 수행되고 있다(K.V et al. |
