Abstract
(EN)
The present invention relates to a concrete composition which is economical and environmentally friendly by: utilizing oxidizing slag which is a by-product generated during an electric arc furnace steelmaking process as a fine aggregate; enhancing the entire strength of the concrete; and drastically reducing the cement content within the concrete, and relates specifically to a high performance concrete composition using slag which comprises 8-16 weight% of rapid-hardening cement, 3-6 weight% of water, 28-59 weight% of fine aggregate, and 30-50 weight% of coarse aggregate, wherein 30-100% of the fine aggregate is slag. Strength can be enhanced and manufacturing costs can be saved by reducing the content of cement constituting the above-mentioned concrete composition and replacing most of the fine aggregate with electric arc furnace oxidizing slag.

La présente invention porte sur une composition de béton qui est économique et écologique, par : l'utilisation de laitier oxydant, qui est un sous-produit généré pendant un processus de fabrication d'acier au four électrique à arc sous la forme d'un agrégat fin ; l'amélioration de la robustesse globale du béton ; et la réduction considérable de la teneur en ciment à l'intérieur du béton, et porte de façon spécifique sur une composition de béton à hautes performances utilisant du laitier, laquelle composition comprend de 8 à 16 % en poids de ciment à durcissement rapide, de 3 à 6 % en poids d'eau, de 28 à 59 % en poids d'agrégat fin et de 30 à 50 % en poids d'agrégat grossier, de 30 à 100 % de l'agrégat fin étant du laitier. La robustesse peut être améliorée et les coûts de fabrication peuvent être économisés par la réduction de la teneur en ciment constituant la composition de béton mentionnée ci-dessus et le remplacement de la plupart de l'agrégat fin par du laitier oxydant de four électrique à arc.

본 발명은 전기로 제강공정에서 발생되는 부산물인 산화 슬래그를 잔골재로 활용하고, 콘크리트의 전체적인 강도를 향상시키면서도 콘크리트 내 시멘트의 함량을 대폭 줄임으로써 경제적이고 친환경적인 콘크리트 조성물에 관한 것으로서, 자세하게는 속경성 시멘트 8~16중량%, 물 3~6중량%, 잔골재 28~59중량%, 굵은골재 30~50중량%를 포함하며, 상기 잔골재의 30~100%가 슬래그인 것을 특징으로 하는 슬래그를 이용한 고성능 콘크리트 조성물에 대한 것이다. 상기와 같이 콘크리트 조성물을 구성하는 시멘트의 함량을 줄이고 잔골재의 대부분을 전기로 산화 슬래그로 대체함으로써 강도를 향상시키고 원가 비용을 절감할 수 있다.
