Fresh polypropylene fibre reinforced mortar andconcrete


Rheological properties

 


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.
