Influence of the rheological parameters of self-consolidating concrete on their durability

Abstract

Mix design and consolidation are key factors for durability ofconventional vibrated concrete. Due their fluidity self-consolidating concrete (SCC) casting is done by free flow underthe effect of their own weight and consolidation is done withoutvibration. It is reasonable to expect that the rheologicalparameters of the SCC have a significant influence on theproperties that determine durability. This paper investigates thepossible links between the rheological parameters and durabilityof SCC. The results show that there is a strong correlationbetween viscosity with Herschel Bulkley model and sorptivitymeasured at different intervals. Most likely, viscosity influencerelative volume of capillary pores of large diameters
