The purpose of our paper is to assess the recycling potential of the mill scale in the composition of mortars, in order to improve the management of industrial wastes from steelmaking in the electric arc furnaces, by identifying the possible solutions for natural resources conservation. For this purpose, the sand from the mortar compositions was replaced, in different proportions, with the steel mills. We have presented the experimental procedures for the physical and mechanical characterizations of the mortars. The experimental results regarding the replacement of the sand with the mill scale, in order to obtain the mortars, show that both the compressive strength and the flexural strength are inferior to the standard sample. As the proportion of the mill scale (replaced by sand) increases, the mechanical strengths of the two samples decrease below the value of the mechanical strengths of the standard sample.
