This paper is the second part of the paper that provides information on representative parameters in electro-chemical chloride extraction. In part one, results of discrete test samples were outlined. A structural element in the form of Reinforced Concrete (RC) slab was constructed and tested to evaluate the ECE performance in a simulated structure. The representative parameters of ECE were determined experimentally. The experimental program investigates chloride and alkali concentration, chloride removal efficiency, transference number and half-cell potential. Test results on RC slab are compatible with those obtained in the Part one of the study on discrete test samples; thereby confirm the capability of applying the method to real structures.
