The increased durability of reinforced concrete with hot dip galvanized rebars

Abstract The influence of hot dip galvanizing on the rebar/concrete adherence was studied. The kinetics of rebars corrosion in high chlorides content concrete was studied by electrochemical methods. Unprotected (black steel) and hot dip galvanized steel were studied. The results show a mechanical resistance improvement of reinforced concrete with hot dip galvanized rebars and a better corrosion performance of hot dip galvanized steel in concrete compared to the black steel.
