Abstract

본 발명은 동일한 배합재료에 의한 동일한 배합설계에서 초고강도 콘크리트 경화체의 강도발현을 극대화할 수 있는 방법에 관한 것이다. 본 발명에 따른 강도발현의 극대화를 위한 초고강도 콘크리트의 관리방법은, 초고강도 콘크리트 배합에서 슬럼프 플로우를 850±50mm 수준으로 배합설계하거나, 초고강도 콘크리트 배합에서 공기량을 1.0~2.0%로 배합설계하거나, 초고강도 콘크리트 비빔에서 먼저 굵은 골재와 실리카퓸을 투입하여 20~40초 동안 건비빔한 후 다른 배합재료를 투입하여 비빔하거나, 초고강도 콘크리트 비빔에서 맨 나중에 물을 투입하여 150~200초간 비빔한 후 200~400초 동안 비빔을 멈추어 그대로 놓아두는 정치(定置)과정을 거친 다음 다시 150~200초 동안 비빔하거나, 초고강도 콘크리트를 무다짐 타설하거나, 초고강도 콘크리트를 타설한 후 14~28일 동안 습윤 양생한 다음 기건 양생하는 것을 특징으로 한다. 이와 같은 특징의 본 발명은 200MPa 이상의 극초고강도 콘크리트로 배합설계되는 경우에는 유리하게 적용할 수 있다.
