Experimental investigation of corrosion effect on bond behavior between reinforcing bar and concrete

External Strengthening of Corrosion-Defected Beam–Column Members Using a CFRP Sheet

“…Torres-Acosta et al [9] found that structural stiffness was reduced linearly with an increase in the level of corrosion. Yafei M. et al [10] investigated the effect of corrosion on the steel-concrete interface bond behavior. They mentioned that when the corrosion loss is less than 2.4% so the corrosive influence on bond strength can be ignored, and the bond behavior is more sensitive between the smooth bar and concrete than deformed bar to corrosion.…”

A Comprehensive Model for the Simulation of Reinforced Concrete Deterioration due to Corrosion

“…Moreover, the corrosion products are not limited to Fe(OH) 2 , but we regard the ferric hydroxide as the corrosion product here, for the sake of simplicity.…”

“…However, reinforced concrete structure has suffered corrosion problems due to aggressive agents from de-icing salts and marine moisture [1]. In addition, corrosion process will impair the carrying capacity of rebars set in the concrete [2,3], and the concrete also suffer spalling and cracking due do the volume expansion of rust layer. However, repairmen and replacement of building components are expensive.…”

Entire Process Simulation of Corrosion due to the Ingress of Chloride Ions and CO2in Concrete

“…For simplicity, these works all assume that the corrosion products are uniformly distributed [1,16,17]. However, that case is only suitable for the laboratory condition, in which the external current is attached to accelerate the corrosion process [9,13,18,19]. According to actual observations, it was found that most of the corrosion distribution patterns are nonuniform [15,20].…”

“…Because cracks can reduce the confinement between concrete and rebars the bond behavior of the RC structure declines drastically [12]. e carrying capacity of the RC structure is also impaired by the corrosion-induced reduction of cross-sectional area of the steel reinforcement [9,[12][13][14][15].…”
