Abstract

PARA REGENERAR UNA OBRA(1) DE HORMIGON ARMADO, SE APLICA CONTRA SU SUPERFICIE EXTERIOR (3) UNA RESERVA (4) DE SOLUCION ELECTROLITICA BASICA CAPAZ DE MIGRAR EN EL SENO DEL HORMIGON, Y SE CONECTA UNA CONEXION (6) ELECTRICAMENTE CONDUCTORA ENTRE LAS ARMADURAS (2) DEL HORMIGON Y UN ELECTRODO EXTERIOR (5) EN CONTACTO CON LA RESERVA DE SOLUCION ELECTROLITICA, PRESENTANDO ESTE ELECTRODO UNA ELECTROPOSITIVIDAD DIFERENTE DE LA ELECTROPOSITIVIDAD DE LAS ARMADURAS. APARECE ASI POR UNA PARTE UNA CORRIENTE OSMOTICA DE DIFUSION ENTRE LA RESERVA DE SOLUCION ELECTROLITICA Y EL AGUA INTERSTICIAL DEL HORMIGON, Y POR OTRA PARTE UNA CORRIENTE ELECTRICA ESPONTANEA QUE CIRCULA EN LA CONEXION ELECTRICAMENTE CONDUCTORA.
