<p>The present invention relates to a binder composition using a by-product of a desulfurization process, and more specifically, to a binder composition which enables to increase activity of blast furnace slag by mixing blast furnace slag with petroleum cokes ash prepared during a desulfurization process of a fluidized bed boiler using petroleum cokes as a fuel, desulfurized slag generated as a by-product in a desulfurization process in an ironworks, or desulfurization dust as stimulants, thereby minimizing a consumption amount of Type I Portland cement which is the most widely used in a construction work. The binder composition using a by-product of a desulfurization process comprises, with respect to 100 parts by weight of blast furnace slag, 5-500 parts by weight of petroleum cokes ash which is prepared during a desulfurization of a fluidized bed boiler using petroleum cokes as a fuel and consists of 61-85 wt% of CaO and 15-40 wt% of SO_3; and 3-300 parts by weight of desulfurized slag micro powder or desulfurization dust which is prepared during a desulfurization process of an ironworks and consists of 40-80 wt% of CaO and 0.5-40 wt% of SO_3, wherein a specific surface area is 3,000-8,000 cm^2/g.</p> |
