Abstract The object of this investigation is crushed dolomite waste that originally is mixture of sand and small size powder fractions. Investigation of physical and chemical property of material showed generally homogeneous mineralogical composition of waste: dolomite CaMg(CO3)2 content is not less than 92 %. Fine-graded and ordinary concrete materials were produced substituting quartz sand with dolomite waste sands. Frost resistance and compression strength of concrete specimens filled with dolomite waste are equal to the concrete filled with traditional quartz sand. Compositions filled with dolomite sand showed higher water absorption and water penetration. Investigations have shown the possibility utilization a dolomite sand waste as substitution of traditional quartz sands.
