Zusammenfassung:The invention concerns a method for treating wood aggregate used for making a cement-based composite, using anhydrous calcium oxide or quick lime in powder form incorporated in the wood aggregate for filling up the wood pores. The hydration of quick lime produces an exothermal reaction reducing moisture, with subsequent reinforcement of the wood hardness after the pores have cooled and closed up as the quick lime is transformed into slack lime. Un procédé de traitement d'un granulat de bois entrant dans la fabrication d'un composite à base de ciment, utilise de l'oxyde de calcium anhydre ou chaux vive en poudre incorporée dans le granulat de bois pour combler les pores du bois. L'hydratation de la chaux vive entraîne une réaction exothermique de réduction du taux d'humidité, suivie d'un renforcement de la dureté du bois après refroidissement et resserrement des pores lors du passage de la chaux vive à la chaux éteinte.
