Abstract
POLARISATION ELECTRIQUE EN VUE DU DECOFFRAGE D’UNE PAROI EN BETON ARME BANCHE Le procédé de commande de la polarisation électrique facilitant le décoffrage d’une paroi en béton armé banché de la face coffrante conductrice de l’électricité d’une banche faisant partie d’un coffrage délimitant un espace coffrant, alors qu’une armature métallique a été disposée dans cet espace et que du béton courant choisi apte à la polarisation électrique, préalablement gâché, y a été coulé et son compactage assuré au moment T1, par application d’une différence de potentiel électrique ΔV entre la face coffrante et l’armature, tel que l’on commande le début de l’application de la différence de potentiel électrique ΔV entre la face coffrante et l’armature, au moment T3 qui est égal à T2 + ΔTr, dans lequel T2 est le moment de la prise du béton, et ΔTr est une durée post-prise du béton, de sorte que l’application de la différence de potentiel ΔV entre la face coffrante et l’armature commence après le début de la prise du béton moyennant la durée post-prise ΔTr, à un moment où le béton bien qu’ayant déjà commencé sa prise est encore apte à être polarisé. Figure pour l’abrégé : figure 17ELECTRICAL POLARIZATION FOR THE RELEASE OF A REINFORCED CONCRETE FORM WALL The process for controlling the electrical polarization facilitating the stripping of a reinforced concrete wall formwork from the electrically conductive shuttering face of a form forming part of a formwork delimiting a formwork space, while a metal reinforcement has been placed in this space and current concrete chosen suitable for electrical polarization, previously spoiled, has been poured therein and its compaction ensured at time T1, by application of an electric potential difference ΔV between the shuttering face and the reinforcement, such that the start of application of the electric potential difference ΔV between the shuttering face and the reinforcement is commanded, at time T3 which is equal to T2 + ΔTr, where T2 is the time of concrete setting, and ΔTr is a post-setting time of the concrete, so that the application of the potential difference ΔV between the shuttering face and the reinforcement begins after the beginning of e the setting of the concrete by means of the post-setting time ΔTr, at a time when the concrete, although having already begun to set, is still able to be polarized.
