TESTS ON BOND OF GALVANIZED REBAR AND CONCRETE CURED IN SEAWATER
It has been claimed that a main concern with using galvanized reinforcement is a possible decrease of the rebar/concrete bond strength. The available results in the literature contradict this claim, and no long-term study results have been found. In this paper, a series of tests is presented that compares the bond of deformed bare rebars with galvanized ones, exposed up to 10 years to a chloride environment in natural seawater. In the case of galvanized rebars, the action of an H sub 2 inhibitor has been considered as well. Results show that galvanized rebars maintain bond characteristics throughout the test period, with values much higher than the minimum requirements. The addition of an H sub 2 inhibitor or the use of cements with a high alkali content have been shown to be irrelevant in the long term.
