The main challenge of this work is using dolomite filler in concrete production. A method for inspecting a fine dolomite group has been developed for evaluation of the possibility of using this dolomite as filler in concrete. The concrete composition has been created, where the traditional sand are replaced totally or partly by the dolomite sand used as a filler. The practical recommendations have been elaborated for using the dolomite processing byproducts for producing concrete and reinforced concrete
