The present invention relates to a binder composition using a circular resource, and more particularly, to a binder composition which is capable of replacing first-class normal cement, which is widely used in construction works, by increasing activity of blast furnace slag by utilizing petroleum coke cinder or sodium sulfate, which is a by-product generated in a firing process of a steelwork or a glass manufacturing process, as stimulant. The binder composition using a circular resource as stimulant according to the present invention includes 10-500 part by weight of petroleum coke cinder containing 61-85 wt% of CaO, and 0.1-50 part by weight of sodium sulfate which contains 10-50 wt% of Na_2O and 10-50 wt% of SO_3 and is a by-product generated in a firing process of a steelwork or a glass manufacturing process, and has a specific surface area of 3,000-8,000 cm^2/g, based on 100 part by weight of blast furnace slag. |
