CHO YOUNG KEUN / LEE BONG CHUN / LEE JUN / KANG YONG HAK / JUNG SANG HWA

The present invention relates to a concrete repairing material containing an alkali-activated binder, and a concrete curing method using the same. In the present invention, an alkali-activated binder which activates blast furnace slag and fly ash into alkali is utilized as a concrete repairing material. Four hours after finishing construction by paving using the concrete repairing material, the concrete repairing material exhibits initial strength of 21 MPa or more as compression strength, thereby reducing traffic opening time in comparison to a conventional concrete repairing material or a concrete repairing method. Also, the concrete repairing material of the present invention can embody excellent adhesion characteristics with conventional a concrete pavement without using an expensive polymer-based material.

본 발명은 알칼리 활성화 결합재를 함유한 콘크리트 포장 보수재 및 그를 활용한 양생방법에 관한 것이다. 본 발명은 고로슬래그 분말 및 플라이애시를 알칼리로 활성화시킨 알칼리 활성화 결합재를 콘크리트 포장 보수재로 활용함으로써, 상기 보수재를 포설하여 시공한 후, 4시간이 경과하면(교통개방시간) 압축강도 21MPa 이상으로 초기 강도를 발현하므로 종래 보수재나 공법보다 교통개방시간을 단축하고, 고가의 폴리머계 재료 없이도 구 콘크리트 포장과의 우수한 부착특성을 구현한다.
