Properties of steel-polypropilene hybrid fibers reinforced concrete

This paper present the results of mechanical properties hybrid reinforced concrete made by adding polypropylene and steel fibers into mixture. For testing purposes were used with hooked ends monofilament fibers. The total 5 batches made: addition fibers, their combination in amount 0,5 % volume. test show that concretes 0.4% 0.1% have better performance compared to other concretes.
