CA 2755558

A method of producing cementitious mixtures containing fly ash as one of the cementitious components, under air entrainment conditions is described. The method involves forming a mixture comprising water, cement, fly ash, optionally other cementitious materials, aggregate, conventional chemical admixtures, and an air entrainment agent and agitating the mixture to entrain air therein. Additionally, at least one amine sacrificial agent is included in the mixture. The cementitious mixtures and hardened concretes resulting from the method and fly ash treated with sacrificial agent, or air entrainment agent/sacrificial agent combinations, are also described.

L'invention concerne un procédé de production de mélanges cimentaires qui contiennent des cendres volantes comme composant cimentaire, dans des conditions d'occlusion d'air. Le procédé comporte les étapes consistant à: former un mélange comprenant de l'eau, du ciment, des cendres volantes, éventuellement d'autres composants cimentaires, un agrégat, des mélanges chimiques classiques et un agent d'occlusion d'air; et agiter le mélange pour y former des occlusions d'air. De plus, au moins un agent sacrificiel d'amine est inclus dans le mélange. L'invention concerne aussi les mélanges cimentaires et les bétons durcis obtenus au moyen du procédé et de cendres volantes traitées avec l'agent sacrificiel, ou de combinaisons d'agent d'occlusion d'air/agent sacrificiel.
