SELF HEALING CONCRETE CONTAINING INORGANIC SELF HEALING MATERIAL
The present invention relates to self-healing concrete mixed with an inorganic self-healing material. The present invention relates to a novel inorganic self-healing material capable of quickly increasing the production amount of the self-healing material when a crack occurs in the concrete. In the present invention, nanocalcite is mixed with normal Portland cement, so that the production of a self-healing hydrate and calcite by means of further hydration is promoted even in a low ion concentration environment through the seed effect of nanocalcite. Accordingly, the production amount of a self-healing material under the same ion concentration condition is significantly increased, and when the nanocalcite is mixed, a mixing amount and an average particle size of the same are optimized, such that self-healing performance is achieved even when a width of a crack is equal to or greater than 0.25 mm.
본 발명은 무기계 자기치유 소재를 배합한 자기치유 콘크리트에 관한 것이다. 본 발명은 콘크리트 균열 발생시 신속한 자기치유 물질 생성량을 증가시킬 수 있는 신규한 무기계 자기치유 소재로서, 보통 포틀랜드 시멘트에 나노 칼사이트(Nano-Calcite)를 배합함으로써, 나노 칼사이트의 시드(seed) 효과로 낮은 이온 농도 환경에서도 지속적인 수화(further hydration)에 의한 자기치유 수화물의 생성 및 칼사이트 생성을 촉진시켜, 동일 이온 농도조건에서 자기치유 물질 생성량을 현저하게 증가시키고, 상기 나노 칼사이트 배합시 혼입량과 평균입자크기를 최적화하여, 균열 폭 0.25㎜ 이상에서도 자기치유성능을 달성할 수 있다.
