COMBINATION ELECTRODE FOR ELECTROCHEMICAL RESTORATION OF CORRODED REINFORCED CONCRETE AND METHOD FOR CONTROLLING SUCH ELECTRODE Russian patent published in 2005 - IPC

FIELD: processes and apparatuses for restoring corroded reinforced concrete.

SUBSTANCE: electrode 1 has stable size and shape. Accumulator 2 for electrolyte and changeable anion-exchange member are designed for multiple use. Central mounting device includes dowel with reference electrode 6 in head, anchor rod and eccentric quick- clamp attachment 5. Anode control system 8 includes power switch. Measuring system 9 is used for determining state of anion exchange member. Surface to be restored is hypothetically divided by separate portions. Initial values, measuring, control and interruption criteria are set for each portion. Each portion is connected to DC source and it is realized continuous monitoring of reference potential at restoration process, voltage change of chloride pickup and cut of pulse controlling turning-off. DC power at restoration is controlled with use of pulse -width modulation.

EFFECT: possibility of multiple use of electrode and optimal matching of working parameters of process.
