Abstract: Due to its advantages during placing, self-compacting concrete (SCC) seems to be a very promissing material for concrete construction. At this moment however, not much information is available concerning the fundamental background of the properties of the SCC. At the Magnel Laboratory for Concrete Research, an extended research programme is going on in order to more fundamentally understand the behaviour of this material. This research project includes the study of the fresh, hardening and hardened SCC, with due attention given to the time-dependent mechanical behaviour.
In this contribution, results are reported concerning the creep and shrinkage of SCC. The measurements are carried out on sealed and unsealed specimens in order to be able to extract basic and drying creep and shrinkage. Different mix compositions are considered, studying different parameters, like cement type, filler type, c/p (cement to powder ratio).
To study the deformations in more detail, the applicability of traditional creep and shrinkage models is investigated. Well-known models like the CEB-FIP Model Code 1990, the ACI-model and the model of de Larrard are evaluated. Some suggestions are made to include the influence of the addition of the fillers in the model of the Model Code.
