Extracción electroquímica de cloruros del hormigón armado: Estudio de diferentes variables que influyen en la eficiencia del tratamiento

Abstract

This paper reports the results of applying electrochemical chloride extraction (ECE) to a series of chloride-contaminated concrete specimens. Experimental conditions were varied to study the efficiency of this technique under different circumstances. The survey covered the possible relationship between efficiency and the location of the sampling point, current density, type of concrete and treatment intermittency. Experiments were also conducted with different reinforcement configurations used in standard structural members such as columns and beams to ascertain the impact of rebar geometry.
