Abstract
Super workable concrete with hiqher flowability and stability was used for this building in order to store things like newspapers which are easily affected by moisture. The reason is that honeycomb and void should be minimized on the finishing surface of concrete. As a result, it was found that compactability of concrete and quality of concrete in structures were improved and this is an excellent technology as a method of rationalizing constructions such as an improvement of working environment and an elimination of laber.
