Abstract: Cements with ground granulated blast furnace slag (GGBFS) addition (CEM II and CEM III) are commonly used in concrete industry, although usually their application in precast concrete was limited due to their lower early strength comparing to Portland cement CEM I. However, on the market cements with GGBFS with high early strength are available. Portland-slag cement CEM II/A-S 52,5 N is such an example, which seems to be suitable for precast applications. In this paper results of research works and industrial experiences with self-compacting concrete containing CEM II/A-S 52,5N are presented. They confirm usefulness of cement CEM II/A-S 52,5N in mentioned application field, also with high fly ash addition
