Resumen

Rheology is a fundamental property to characterize the workability, consistency, and fluidity of a concrete. This study investigates the rheological behaviour of UHPC concrete for four (4) percentages of variation of superplasticizer, with respect to the reference dosage. A coaxial rheometer was used for determination of flow curves of tested samples. These flow curves and the relationship between the yield stress and mini-slump flow test [1] were measured from a time of 36 minutes and up to two (2) hours after having come into contact with the liquid phase and solid phase in the mixing process of the UHPC. The variation of the compressive strength for the different percentages of SP used in this study was determined.
