ABSTRACT: Concrete is the major constituent of continuous flight auger (CFA) piles, hence, understanding the concrete mixture behaviour and optimizing its design are essential. A laboratory study was undertaken to evaluate the fresh and hardened properties of CFA concrete mixtures incorporating treated oil sands waste (TCCW). Variation of hardened properties with curing time has been quantified. Results show that TCCW addition had an insignificant effect on the concrete flowability. Strength gaining rates for concrete mixtures incorporating TCCW were near that of the control mixture. Results suggest that TCCW can be used in CFA piles which will lead to both economic and environmental benefits.
RÉSUMÉ: Le béton est le constituant majeur des pieux à tarière continue (CFA), par conséquent, la compréhension du comportement du mélange de béton et l'optimisation de sa conception sont essentielles. Une étude en laboratoire a été raîches et hydratées du mélange de béton CFA en incorporant des déchets de sables bitumineux traités (TCCW). La variation des propriétés du béton hydraté en fonction du temps de cure a été quantifiée. Les résultats montrent que le TCCW avait un effet négligeable sur la fluidité du béton. Le taux de résistance gagné dans les mélanges de béton incorporant le TCCW était près de celui du mélange de contrôle. Les résultats suggèrent que le TCCW peut être utilisé dans les pieux CFA, conduisant à des avantages économiques et environnementaux.
