Abstract

L'invention concerne le préchauffage du béton juste avant sa coulée. Le dispositif de préchauffage comprend au moins une benne 2a à axe vertical, dont l'orifice de sortie 12 est excentré par rapport à cet axe, et plusieurs électrodes verticales 45a, 45b et 45c dont deux (45a, 45b sont plus courtes et de section plus grande que la troisième (45c). Application au préchauffage du béton sur le chantier avant sa coulée dans des coffrages ou dans un atelier de fabrication de pièces de béton.
