Abstract: Compressive creep tests were performed at early age on concrete for which 75% of Portland cement is substituted by blast furnace slag and limestone filler. An adapted version of the Model Code 2010 creep function (MC2010) is used to model basic creep. It is observed that high substitution rate of cement by slag and limestone filler leads to a significant change in the evolution of the viscoelastic properties of concrete till the end of the second peak of hydration due to slag. After, the viscoelastic behaviour is very similar to ordinary concrete with equivalent water-to-binder ratio.
