Abstract

Abstract

The primary and secondary factors of influencing the efficiency of electrochemical chloride extraction(ECE) were investigated by orthogonal test method,the results show that current density has the largest effect,the second is the type of electrolytes and water to cement ratio of concrete,initial chloride content has the least effect.Mercury intrusion porosimetry analysis for the samples ECE-treated and untreated ones were performed,for the ECE-treated samples porosity less than 30nm near rebar increased and that far from rebar decreased.When an electrolyte composed of 0.001 mol/L Li2B4O7 and saturated Ca(OH)2 solution and electrical current density of 3 A/m2 were adopted,the best desalination efficiency can be achieved.
- orthogonal test,
- electrochemical chloride extraction(ECE),
- current density,
