In the article was attempt to evaluate the adhesion of steel fibers to the concrete matrix after their mechanical treatment. The processing of the fibers consisted of developing on of their surface by an abrasive treatment with the use of electrocorundum. In the first stage of the research, the surface of the fibers was assessed (before and after abrasion treatment) using the selected metallographic techniques. A micro scale images of the fibers surface were made and compared, as well as the surface roughness of the fibers was determined. The second stage of the research concerned the direct evaluation of adhesion using the pull-out test.
