Abstract
L'invention concerne une composition d'une pouzzolane activée comprenant un mélange de fines particules broyées ensemble d'une pouzzolane naturelle initialement non activée et d'un matériau cimentaire supplémentaire (SCM) différent de la pouzzolane naturelle initialement non activée. La pouzzolane naturelle initialement non activée peut comprendre des cendres volcaniques ou un autre dépôt pouzzolanique naturel ayant une teneur en humidité d'au moins 3 %, et la composition de pouzzolane activée peut avoir une teneur en humidité inférieure à 0,5 %. La pouzzolane naturelle initialement non activée peut avoir une taille de particule inférieure à 1 mm avant le broyage en commun avec le SCM. Le SCM utilisé pour activer la pouzzolane naturelle initialement non activée peut être initialement grossier ou granulaire avec une taille supérieure à 1-3 µm et peut comprendre du laitier de haut fourneau granulé, du laitier d'acier, d'autres scories métallurgiques, de la pierre ponce, du calcaire, des agrégats fins, du schiste, du tuf, du trass, de matériaux géologiques, des déchets de verre, des tessons de verre, du basalte, des fritters, des céramiques, des briques recyclées, du béton recyclé, des matériaux réfractaires, d'autres déchets industriels, du sable ou des minéraux naturels.
