Title:
HIGH PERFORMANCE CONCRETE COMPOSITION USING SLAG
Document Type and Number:
WIPO Patent Application WO/2012/138088
Kind Code:
A2
Abstract:
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.
