  • Verification of the Use of Slag Aggregate Scientific.Net

    The paper deals with on comparison of selected properties of slag aggregate and natural aggregate in concrete. In mixtures was used as filler the slag aggregate from Koněv heap in Kladno and for comparison was used natural aggregate from Tovačov and Hrabůvka that is commonly used in concrete. The aim of this work was to verify whether this slag aggregate can be used in cement based mixtures.
