Shrinkage behavior of self-compacting concrete (SCC) can be different from that of traditional vibrated concrete, because of different paste and aggregate volumes. For traditional concrete, shrinkage can be estimated based on shrinkage results obtained on paste level. Based on homogenization techniques, Le Roy developed a model relating the shrinkage of concrete to the shrinkage of the representative cement paste, considering a granular coefficient taking into account the elastic properties and the concentration of the aggregates. By means of an extended experimental program, the applicability of this model to the case of SCC has been verified. Furthermore, some known results on the influence of water/cement ratio and filler/cement ratio have been confirmed and can be explained by porosity results
