Application of an Improved Empirical Model for Rheology Prediction of Cement Pastes Modified with Filler from Manufactured Sand
Abstract
There isaneedforsimplebutprecisepredictionmodelsforproportioningconcretewithmanufacturedsand,foruseinready-mixconcreteproduction. Forthelasttwodecades,theparticle-matrix model has been used in Norway for proportioning and prediction of concrete flow basedonthepropertiesandproportionsoftwoconcrete phases:coarseparticlesandfillermodified cement paste (matrix). This paper presents experimental testing of 117 cement pastes of which107containfiller,i.e.particles<125microns, frommanufacturedsand.Basedoncompositionsandpropertiesofingoingmaterialsinthesemixes,anempiricalequationisdevelopedthatpredictstherheologicalpropertiesplasticviscosity,yieldstress,flowresistance ratioandmini slumpflow.Optimizationbyregressionanalysisprovidesapractical microproportioning equation that readily can be used as input in concrete proportioning with the particle-matrix model. The equation provides a coefficient of determination R<sup>2</sup> = 0.98 for plastic viscosity, R<sup>2</sup> = 0.95 for mini slump flow, R<sup>2</sup> = 0.91 for flow resistance ratio and R2 = 0.80 for yield stress.
