Verification of the Use of Slag Aggregate of the Heap Koněv into Concrete

Abstract:

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. In the the experiment, the basic physical-mechanical parameters of both types of aggregates were determined, mixtures were proposed and then tested. Durability properties were also verified.
