One equipment seller provides these estimates for contractors and industry to followBond Behavior between Steel and Concrete in Low Level ,, The corrosion level was ranging from 0% to 4% in mass loss In low level corrosion up to 1% of corrosion level, the bond stress increases causing a decrease in average crack spacing For higher corrosion levels the decrease of average crack spacing is attributed to the decreasing of concrete tensile strength caused by cracks around corroded bar.
