| Description | The main role of dispersed short discrete fibers as a reinforcement for concrete is to prevent formation of shrinkage cracks, their spreading in the structures and increasing resistance of concrete to high temperatures. The plasma treatment of polypropylene (PP) fibers was discussed as a method that leads to the increasing of surface freee energy of polypropylene, accordingly better adhesion between the fibers and cement matrix. The plasma treatment improved the surface wetting properties of PP fibers. The three point bending test confirmed the improving of the mechanical performances of concrete with plasma treated fibers as a reinforcement. |
