    摘要: 콘크리트의 건조수축 균열문제는 콘크리트 구조체의 안전성, 내구성, 미관 등에 영향을 주는 중요한 원인이 되고 있다. 이러한 균열에 대한 보수/보강의 기술이 발전하였다 하더라도 근본적으로 균열에 의한 문제를 해결할 수 없는데, 가장 직접적인 해결방법은 콘크리트 자체의 수축을 저감하여 즉, 저수축의 콘크리트를 제조함으로 균열발생 확률을 낮추는 것이다. 일반 콘크리트 자체의 수축저감 방법으로 단위수량 감소, 단위시멘트량 감소 및 잔골재율을 낮추는 등 배합적인 방법이 있으나 수축저감에 한계가 있고, 팽창재/수축저감제 등 각각의 혼화재료를 사용하는 방법이 있으나 역시 수축저감의 한계 및 사용상에 번거로움 등이 제기되고 있다. 그러나 본 발명에 따라 수축저감제, 팽창재 및 플라이애쉬를 일정비율로 혼합하여 개발된 수축저감형 혼화재를 사용하면 복잡한 설비 및 번거로운 배합조정 없이, 현재 일반적으로 사용하는 플라이애시 등 혼화재와 동일한 방법으로 사용함으로서 일반 콘크리트의 건조수축을 크게 저감할 수 있다.
