고류동(高流動)페이스트의 류동특성(流動特性)에 미치는 멜라민계 고성능감수제의 영향 = The Effect of Melamine Sulphonate High-Range Water Reducing Agent to the Fluidity of High-Flowability Paste

다국어 초록 (Multilingual Abstract)

The viscosity of high-flowability paste is very high compared to normal concrete for the low water-binder ratio(W/B). Therefore, high-flowability concrete is positively necessary to high-range water reducing agent. High-Flowability paste can make much higher fluidity with no occurrence of segregation, by its higher viscosity and lower yield value than normal concrete. The flowability of high-flowability paste must be evaluated not only by convention consistency test such as slump test but also by the base of the rheological properties of the fresh concrete. The purpose of this study is to analyze the fluidity of high-flowbility paste according to the addition ratio of the Melamine Sulphonate high-range water reducing agent; high-flowbility paste is considered as Binghham plastic fluid with the rheology parameters of the plaste viscosity and yield value.
