Development of Fly Ash Super-Flowing Concrete
플라이애쉬를 사용한 2성분계 초유동 콘크리트의 개발
Abstract
In this study, several rheological properties of binder pastes and concrete are investigated for the development of commercially available fly ash super-flowing concrete. Fly ash contents with 5 leves(0, 10, 20, 30, 40%), slag contents with 6 levels(0, 5, 15, 25, 35, 45%), and water-binder ratios with 4 levels(30, 33, 36, 39%) are selected for test variables to evaluate the super-flowing characteristics of binder pastes. For the estimation of the workability of super-flowing concrete, slump flow, funnel time, box height, and L-flow are measured and compared. As the results, the flow is decreased and the viscosity is increased with increasing fly ash content. Super-flowing concrete is succesfully produced with 30% fly ash replacement.
