Self-healing composition and concrete repair composition thereof
The present invention relates to a self-healing composition comprising: a composition (1) including 90 to 94 wt% of calcium hydroxide, 3 to 6 wt% of sodium carbonate, and 2 to 5% wt% of bentonite; and a liquid (10) for kneading, which is mixed in the composition (1) to knead the composition (1), wherein the composition (1) and the liquid (10) for kneading are mixed in a weight ratio of 9:1 to 7:3. Calcium hydroxide, sodium carbonate, and bentonite are substances which react with halogen ions, such as CO2, Cl-, Br, and degradation factors, such as SO4, present in a salty environment, and react with water or ions above to generate products such as C-H, gypsum, ettrigite, CaCO3, and C-S-H, filling a crack surface. The present invention relates to the self-healing composition capable of self-healing by the moisture penetrating through a crack when a crack occurs in a vulnerable environment, and the concrete repair composition using the same.
본 발명의 자가치유 조성물은 수산화칼슘 90~94 중량%; 탄산나트륨 3~6 중량%; 벤토나이트 2~5 중량%;를 포함하는 조성물(1), 조성물(1)을 반죽하기 위해 조성물(1)에 혼합되는 반죽용 액상(10);을 포함하되, 조성물(1)과 상기 반죽용 액상(10)은 9:1~7:3의 중량 비율로 혼합된다. 수산화칼슘, 탄산나트륨, 벤토나이트는 염해환경에 존재하는 CO2, Cl-, Br 등과 같은 할로겐 이온과 SO4 와 같은 열화인자들과 반응하는 물질로서, 물 또는 위의 이온들과 반응하여 C-H, gypsum, ettrigite, CaCO3, C-S-H와 같은 생성물을 발생시켜 균열면을 매워주게 된다.
