Abstract
While many studies have evaluated the corrosion performance ofhot-dip galvanized reinforcement (ASTM A767), few have evaluatedthat of the newer continuously galvanized reinforcement(ASTM A1094). This study compared the corrosion resistance ofASTM A767 and A1094 reinforcement, along with uncoated reinforcement, using the Southern Exposure (SE) and cracked beam(CB) tests. The galvanized reinforcement was tested both with andwithout damage to the coating, as well as after bending the bars.Both ASTM A767 and A1094 reinforcement exhibited better corrosion resistance than uncoated reinforcement, but corrosion rates on both types of galvanized reinforcement increased when the bars were bent. ASTM A767 and A1094 reinforcement exhibited similar corrosion resistance and can be used interchangeably.
