CONCRETE COMPOSITION USING FE-SI INDUSTRIAL BY-PRODUCTS

摘要

The present invention relates to a concrete composition using Fe-Si industrial by-products and, more specifically, to a concrete composition using Fe-Si industrial by-products, which utilizes by-products generated in a process of producing high purity ferrosilicon (Fe-Si), used as an additive in domestic advanced electrical steel, and applies the by-products as a cement binder. According to a desirable embodiment of the present invention, the concrete composition comprises: 120-160 kg/m^3 of water; 330-370 kg/m^3 of cement; 724-764 kg/m^3 of fine aggregate; and 906-1306 kg/m^3 of coarse aggregate, with respect to the unit volume of the concrete composition, wherein 5-10 wt% of ferrosilicon industrial by-products are replaced and added with respect to 100 wt% of the cement.
