Abstract
본 발명은 슬래그(slag) 미분말은 함유하는 저발열 저수축 콘크리트 조성물에 관한 것으로서, 더욱 상세하게는 콘크리트 조성에 있어서 시멘트의 리부를 슬래그 미분말로 치환하여 사용하거나 슬래그 시메트를 사용하고 혼화제를 다량 첨가함으로써 단위시멘트량 및 단위수량을 대폭 감소하여 수화발열량 및 건조수축을 저감시켜 매스 콘크리트(mass concrete)공사나 긴 벽체 공사 등을시행할 경우 균열을 방지할 수 있는 새로운 조성의 저발열 저수축 콘크리트 조성물에 관한 것이다.The present invention relates to a low calorific low shrinkage concrete composition containing fine slag powder, and more particularly, in the concrete composition, by using the slag fine powder in the concrete composition by replacing the slag fine powder or using a slag simet and adding a large amount of admixture. By significantly reducing the amount of unit cement and the amount of unit, it reduces the amount of hydration calorific value and dry shrinkage, so that it can prevent cracking when mass concrete construction or long wall construction is performed. It is about.
