INFLUENCE OF CORROSION OF BRASS METALIZED PLAIN STEEL BARS ON BOND STRENGTH WITH CONCRETE
Original language description
This paper evaluates the influence of thickness of metallized brass coating on bond strength of smooth bars in concrete. In the experiment, corrosion stability of the coating was evaluated considering the initial corrosion damage caused by alkali pore solution of fresh concrete. Bond strength was evaluated for both normal strength concrete (NSC) and ultra-high performance concrete (UHPC). Further, the corrosion attack on coating was studied microscopically and the relationship between its character and final bond strength was described. The results suggest that corrosion resistance of such coated reinforcement and its bond strength are related to the initial alkalinity of both fresh concretes and the additional alkalinity of UHPC. The results are discussed with regard to the trend of using dispersed steel concrete reinforcement coated with brass in high-performance composites.
