The Characteristic of Fresh Properties of Antiwashout Underwater Concrete with Variation of Fly Ash

플라이애쉬를 혼입한 굳지않은 수중불분리성 콘크리트의 특성에 관한 연구

In recently, though the development of antiwashout admixture, if's possible to construct in underwater with the concrete which is improved segregation resistance of material, filling and self-leveling. It is generally to use this method with Europe and Japan as the central figure, and also the construction case is reported in korea. There's some advantages to add the fly ash in plain concrete. The objective of this study is to find the characteristics of fresh underwater antiwashout concrete which is followed by the blend rate of fly ash.
