Abstract

본 발명은 삼성분계 시멘트를 함유하는 저발열 저수축 콘크리트 조성물에 관한 것으로서, 더욱 상세하게는 콘크리트 조성에 있어서, 시멘트의 일부를 프라이애쉬(fly-ash)와 슬래그(slag) 미분말로 치환하고 혼화제를 다량 첨가함으로써 다위시멘트량 및 다위수량을 대폭 감소하여 수화발열량 및 건조수축을 저감시켜 매스 콘크리트(mass concrete)공사나 긴 벽체 공사등을 시행할 경우 균열을 방지할 수 있는 새로운 조성의 저발열 저수축 조성물에 관한 것이다.The present invention relates to a low calorific low shrinkage concrete composition containing ternary cement, and more particularly, in concrete composition, a part of cement is replaced with fly-ash and slag fine powder and the admixture is mixed. Low amount of heat generation and low heat generation with new composition to prevent cracking when mass concrete construction or long wall construction is performed by greatly reducing the amount of multi-cement cement and the number of water by reducing the amount of hydration. It relates to a composition.
