Rational use of highly dispersed metal waste is an important issue of material science and environment protection. The quantity of the powdered metallic materials used in industry is steadily increasing; they are especially widely used in the enterprises producing iron powders, in metal sheet production, as well as in abrasive machining. This paper presents an analysis of several kinds of metal waste such as iron and steel powders, mill scales, steel punching, metal shavings and other iron-containing waste from mechanical engineering and metallurgy industries, and the possibility of their use in the manufacturing of concrete products like fillers. This study investigates properties of the samples of the concrete manufactured using highly dispersed metallic fillers. The highest density obtained is in the range of 4000 - 4500 kg/m3. The common characteristics of the aforementioned materials are their low cost, availability and thus the potential for large production volumes, need for recycling, and tendency to further oxidation and corrosion.
