EFFECT OF USE OF GALVANIZED STEEL ON THE DURABILITY OF REINFORCED CONCRETE

Results of atmospheric exposure with cyclic application of NaCl solution on prestressed black and galvanized steel reinforcing bars are reported. Fatigue tests were conducted after 8 months. High strength reinforcing steel bars require limited crack widths for proper durability, so galvanized bars have an added safety factor in aggressive exposures. After vibration testing to failure, black bars were rusted at cracks while galvanized bars showed little attack. Concrete adhered tightly to galvanized bars near cracks. Tests showed galvanized bars lost less fatigue strength than black bars, and that they could tolerate greater crack widths.
