Abstract: In the paper was demonstrated that Calcareous Fly Ash (CSF) or cements that contain CFA as main component – CEM II/A-W, CEM II/B-W, CEM IV/B-W, CEM II/A-M (V-W), CEM II/B-M (LL-W) – can be successfully used in self-compacting concrete (SCC). Cements that contain CFA as main component show better performance in SCC then CFA added directly to concrete. However, CFA presence more than 20-30% may worse flowability and fasten flowability loss of SCC and worse its robustness in varying temperatures. By using cement “CEM V/A (S-W)”, SCC was obtained with workability similar to SCC of cement CEM I..
