Abstract

In a process for the removal of corrosive ions of reinforced concrete, the concrete is moistened with water or electrolyte over a suitable time period and thereafter is dried over a suitable time period. Moistening and drying is repeated as required. Simultaneously with or after the moistening/drying the concrete is electrolysed by the application of electrical direct voltage, whereby the reinforcement of the concrete is used an an electrode. Calcium hydroxyde is used as electrolyte.
