A process for the electrochemical treatment of concrete |
摘要 |
<p>A process for the electrochemical realkalization of reinforced concrete comprises passing a direct electric current between an anode associated with a layer of alkaline electrolyte applied to an external surface of the concrete and a cathode which is located internally in the concrete. The process causes the internal pH of the concrete to increase and a surface layer of the concrete to be impregnated with the electrolyte solution and which comprises a solution of potassium carbonate of concentration at least 0.3 Molar. The process may be applied to concrete a zone of which has a pH of less than 10.0 and the process continued until the pH reaches a level of at least 10.5, preferably at least 11.0.</p> |
