| Zusammenfassung: | A fast-curing geopolymer according to the present invention includes metakaolin, calcium compounds, carbon fiber, dry (fumed) silica having a specific surface area of 150 to 250 m^2/g, and an alkali activator, to have high brittleness, fast curing, free molding, and also excellent non-combustible performance, so that the fast-curing geopolymer can be used as a non-abrasive finishing composite with fire resistance performance and structural stability, and can be applied as a repair and reinforcement material of a concrete structure requiring molding based on fast curing and irregular shapes.
본 발명에 따른 고속경화형 지오폴리머는 메타카올린; 칼슘화합물; 탄소섬유; 비표면적이 150~250 m2/g인 건식(fumed) 실리카; 및 알칼리활성제를 포함하여, 높은 취성을 가지며, 경화가 빠르고, 성형이 자유로우며, 불연 성능 또한 뛰어나기에, 내화 성능에 구조적으로 안정한 불연마감재 복합재로 사용될 수 있고, 빠른 경화 및 불규칙적인 형상으로 성형이 필요한 콘크리트 구조물의 손상 및 파손 부위의 보수 보강재로서 적용이 가능하다. |
