In this study, the rheological parameters of polypropylene fibre reinforced fresh mortar (PFRFM) and polypropylene fibre reinforced fresh concrete (PFRFC), such as yield value g and plastic viscosity h, were determined. PFRFM and PFRFC behave according to the Bingham or nonlinear Hershell-Bulkey model. The rheological parameters were determined using two rheometers, one for mortars and the other for concrete. The objective of this research was to determine the influence of w/c ratio, superplasticizer dosage (SP), fibre volume fraction, and fibre length on the rheological properties of PFRFM and PFRFC.
