摘要：

The influence of selected composition's factors on the rheological properties of concrete for HPSCC and their changes over time was aim the study presented in paper. HPSCC is characterised by its rheological properties. These properties are critically influenced by the timing of the casting process. Using rheometry, the links between slump flow (yield stress g), slump flow time (plastic viscosity h) and composition of HPSCC mix and time are investigated. A statistical model highlighting the relative roles of the elements of mix design is proposed. We conclude that the cement paste content and w/b ratio are there only two significant parameters of the mix design due to the appropriate rheological properties. (C) 2016 Elsevier Ltd.
