Abstract: The influence of mineral additions and chemical admixtures on both setting and volumetric autogenous shrinkage of SCC-equivalent mortars is studied by means of respectively the Vicat needle and the "condom" method. All experiments are performed in the framework of a MSc thesis at the Reyntjens Laboratory.
The investigated parameters are: the type of mineral addition (limestone powder, quartz powder and fly ash), the type of cement (Portland cement CEM I 52.5 R HES and blast furnace slag cement CEM III/A 42.5 N LA) and the applied dosage of chemical admixture (i.e. a PCE-superplasticizer). Besides the SCC-equivalent-mortars (SCM), two traditional concrete-equivalent-mortars (TCM), for each type of cement, are studied.
