The present invention relates to a concrete composition in which the substitution rate of a silica-based slag for concrete is increased using a liquid activating agent and, more specifically, to a concrete composition in which the substitution rate of a silica-based slag for concrete is increased using a liquid activating agent, wherein the liquid activating agent is used to increase the substitution rate of silica-based slag for concrete with respect to cement, the silica-based slag being obtained by finely pulverizing, to at least a cement particle standard, granulated ferronickel slag (prime sand), one of the industrial byproducts of ferronickel, which is a steel raw material product. According to a preferable embodiment of the present invention, the concrete composition comprises: 165-169 kg/m3 of water; 231-374 kg/m3 of cement; 803-883 kg/m3 of fine aggregate; 923-931 kg/m3 of coarse aggregate; and 12-22 kg/m3 of a liquid activating agent per unit volume of the concrete composition ...
