A Study on the Mock-up Test of High-Fluidity Concrete Using Viscosity Agent and Fly-Ash |
| Abstract |
Recently, great effort and investment been ceaselessly made in order to achieve economical made in order to achieve economical production by applying new methods like minimanization of man-power into construction field because there have been increasingly avoidance of 3D works, on the decrease and old age of skilled labors. As above situation, high fluidity concrete has been spotlight in construction field. Accordingly, in this study, for deve1oping the high fluidity concrete within the range of 210~300kg/cm2 of compressive strength, we have been focused on the development and practical using of high fluidity concrete with viscosity agent by appling mock-up test with high fluidity concrete develped in laboratory experiment. Not only good fluidity, segregation-resistibility, placeability and strength development, but also, prevention of settlement, decreasing of hydration heat can be accomplished. But the countermeasure on the delay of setting time and increasing of lateral pressure should be considered. |
