We applied super workable concrete to concrete construction by upside-down method for the first time in this country. We made the best use of characteristics of super workable concrete that is superior in concrete flowability and stability and studied systematically concrete construction by upside-down method. As this result, we made it clear that this method is very economical from the points of less honeycomb, void and sand streak and small space at horizontal construction joint and furthermore rationalization of construction and elimination of laber.
