Abstract

L'invention a pour objet un procédé de récupération de béton frais non utilisé, comprenant : 1) avant la prise du béton, l'additon d'un retardeur de prise en une quantité suffisante pour retarder l'hydratation pendant encore 90 heures au maximum, 2) éventuellement, à la fin de la période de retard souhaitée, la dilution du béton retardé avec du béton frais, et 3) l'addition d'un accélérateur au béton retardé pour lui redonner un état durcissable.
