CORROSION OF ALUMINUM ALLOY BALUSTERS IN A REINFORCED CONCRETE BRIDGE

A BRIDGE BUILT NEAR THE SEA IN THE REPUBLIC OF SOUTH AFRICA WAS BADLY DAMAGED BY CORROSION OF THE ALUMINUM ALLOY BALUSTERS. INVESTIGATION SHOWED THE PRIMARY CAUSE OF CORROSION WAS GALVANIC COUPLING OF THE ALUMINUM BALUSTERS AND THE STEEL USED TO REINFORCE THE CONCRETE. PAINTING THE ALUMINUM WHERE IT MET THE CONCRETE REDUCED THE POSSIBILITY OF THIS TYPE OF CORROSION. /AUTHOR/
