MICROCAPSULES FOR SELF-HEALING CONCRETE USING MICROORGANISMS AND METHOD FOR PRODUCING SAME, AND SELF-HEALING CONCRETE COMPOSITION CONTAINING MICROCAPSULES
The present invention relates to: microcapsules for self-healing concrete in which a large amount of calcium carbonate is generated by urea-decomposing microorganisms when cracks occur in concrete, such that cracked areas can be self-healed; a method for producing the microcapsules; and a concrete composition containing the microcapsules. The microcapsule for self-healing concrete according to the present invention may comprise a core including spores formed by co-culturing a urea-decomposing microorganisms that decompose urea to produce carbonate ion (CO3 2-) and non-urea degrading microorganisms that do not decompose urea, and a shell surrounding the core.
La présente invention concerne : des microcapsules pour béton autoréparable où une grande quantité de carbonate de calcium est générée par des micro-organismes décomposant l'urée quand des fissures se produisent dans le béton, de façon que les zones fissurées puissent s'autoréparer ; un procédé de production des microcapsules ; et une composition de béton contenant lesdites microcapsules. La microcapsule pour béton autoréparable selon la présente invention peut comprendre un cœur comprenant des spores formées par co-culture de micro-organismes décomposant l'urée qui décomposent l'urée pour produire l'ion carbonate (CO3 2-) et de micro-organismes ne décomposant pas l'urée qui ne décomposent pas l'urée, et une coque entourant le cœur.
본 발명은 콘크리트의 내부에서 균열이 발생했을 때 우레아 분해성 미생물에 의해 다량의 탄산칼슘이 생성되어 균열 부위를 자기치유할 수 있는 콘크리트 자기치유 마이크로 캡슐 및 그 제조 방법, 그 마이크로캡슐을 포함한 콘크리트 조성물에 관한 것으로, 본 발명에 따른 콘크리트 자기치유 마이크로 캡슐은, 우레아(urea)를 분해하여 탄산이온(CO3 2-)을 생성하는 우레아 분해성 미생물과 우레아를 분해하지 않는 우레아 비분해성 미생물을 공배양하여 형성된 스포어(spore)를 포함하는 코어와, 상기 코어를 둘러싸는 쉘을 포함할 수 있다.
