Currently buildings in Korea get ultra higher-storied by rapidly changed technology of construction and a dense population. However, Korea uses high-price silica fume depending on import in the whole quantity generally to be manifested compressive strength for ultra high-rising buildings and currently has a lot of difficulties in applying high-strength concrete to the field by
increase of concrete’s unit price according to using silica fume. Therefore, the study enforced experiments, setting up each kind of water-binder rates and fin aggregate rates to achieve design standard strength and slumpflow of its target and applying each king of additives to analyze engineering properties of high-strength concrete with high-strength binder with which we can replace silica fume. As the result, high-strength binder showed better tendency than the existing silica fume in fluidity and early strength properties.
