摘要
The present invention relates to an eco-friendly, non-cement, and ultra-rapid hardening binder composition for concrete and an ultra-rapid concrete composition including the same. The binder composition includes blast furnace slag containing silica fume, reduced steelmaking slag, calcium hydroxide, anhydrous gypsum, calcium sulfo-aluminate, a water reducing agent, a curing accelerator, and a curing delay agent. The ultra-rapid hardening composition includes the binder composition, aggregate, and water. The binder composition prepared by using a method of the present invention uses the blast furnace slag, silica fume, and quenched and reduced steelmaking slag which are industrial byproducts in order to reduce the carbon emissions in a general Portland cement production process, lower the manufacturing cost, and show excellent compatibility with concrete when applied to the concrete while enhancing the adhesion, compression strength, water resistance, durability, oil resistance, heat resistance, freeze-thaw resistance, chemical resistance, and abrasion resistance.
