Abstract
Purpose of this research is deducing optimum pretreatment method of electric arc furnace slag from comparing and investigating the properties of electric arc furnace slag and electric arc furnace slag concrete by existing pretreatment method and surface pretreatment method being used by this research. Besides, as the surface pretreatment method, the method of naturally drying for 6 hours after impregnating with an inorganic type silica solution for 1 day was used. From the results, comparing the hot water treatment method, surface treatment method being used by this research is more effective. Therefore, it is judged that surface treatment method is more effective in the decrease of expansibility of electric arc furnace slag and practical use.
