Efficiency of Different Electrolytes on Electrochemical Chloride Extraction to Recover Concrete Structures under Chloride-Induced Corrosion

Figure 9

Visual aspect of bars after ECE treatment and immersion in hydrochloric acid (HCl, sp gr 1.19) at 25°C for 2 hours to clean the rust. Bars were brushed in addition for better results. The following cases depicted are in order from specimens treated with water, lithium borate, and calcium hydroxide, respectively, (a) right after treatment and (b) after rust cleaning.
