Utilisation a waste of stone processing in production of other kinds products is an actual task for stone-cutting enterprises. In this study, the possibilities of using basalt dust generated during sawing, grinding and polishing of basalt and related minerals in the manufacture with concrete are studied. Three groups were prepared with different content of basalt dust - 0 %, 5 % and 20 %. After the final hardening performance of the concrete, the compressive strength testing was conducted on the specimens. The results showed that the addition (5%) added basalt dust practically did not reduce the strength ratio practically, the increase of basalt dust content up to 20% caused an average 16% reduction in the strength of the specimens. The fracture character that occurred in the specimens containing basalt dust corresponded to the fracture character that happened to similarly shaped concrete products.
