    초록 This study conducted a series of studies to find alternative ways to use Chlorine Bypass System-dust(CBS-dust) in cement production. The results of engineering characteristics of CBS-dust are summarized as follows. First of all, the density of CBS-dust is 2.40, lighter than cement and the pH was 12.50 which was strong alkaline. In terms of particle size, it was 11.70 μm which was finer than cement. With chemical properties, calcium oxide(CaO) was the highest as 35.10 %, potassium oxide(K2O) was 32.43%, potassium chloride(KCl) was 19.46%, sulfur oxide(SO3) was 6.81%, and the remaining chemical components are SiO2, Fe2O3, Al2O3, MgO, and the like. Therefore, if CBS-dust is used as early-strength chemical admixtures in the concrete secondary products that use a large amount of mineral admixtures without rebar, it can be an effective method for increasing the strength of concrete as an alkali activator and preventing early-frost damage of Cold Weather Concrete.
