Abstract

In this paper, the effect of the mix composition on rheological behavior of a mixture is studied by considering a two-phase model for a mixture. A mixture is decomposed into a granular and a paste phase. Paste itself is divided into the void paste and the excess paste. The slump test is used for evaluation of rheological behavior of a mixture. The results show that the granular-cement paste mixtures can be split into three main classes viz Granular-High Paste, Granular-Intermediate Paste and Granular-Low Paste. In Granular-High Paste class, the behavior is governed by the excess paste and the capacity of deformation of mixtures is maximal. In Granular-Low Paste class, the behavior is governed by the void paste and the capacity of deformation of mixtures is minimal. In Granular-Intermediate Paste class the behavior is determined by both the excess paste and the void paste, and the deformability is in between that of the two other extreme cases.
