Titre : Selection of an effective ASR-prevention strategy for use with a highly reactive aggregate for the reconstruction of concrete structures at Mactaquac generating station Type de document : texte imprimé Auteurs : Sean Hayman, Auteur Année de publication : 2012 Article en page(s) : pp. 605–610 Note générale : Bibliogr. Langues : Anglais (eng) Mots-clés : Alkali-aggregate reaction ; Fly ash ; Granulated lastfurnace slag ; Pozzolan Résumé : Mactaquac Generating Station was constructed in the mid 1960's and is located in the province of New Brunswick in Eastern Canada. The effect of ASR expansion on the concrete structures of the station were first noticed approximately 10 years after construction and, ASR was conclusively diagnosed in 1986. Since 1985, various remedial measures have been undertaken to mitigate the effects of concrete expansion. Eventually reconstruction of the concrete structures will be necessary and current projections are that replacement should be complete by 2030. Due to the lack of any suitable locally-available non-reactive aggregate, consideration is being given to using the same source of reactive aggregate for reconstruction.
This paper describes a research study to determine the optimum strategy for preventing deleterious ASR expansion with this aggregate. The options being evaluated include the use of pozzolans and slag, limiting the alkali content of the concrete, and the use of chemical admixtures. Methods of evaluation include accelerated laboratory tests and field exposure of large blocks.En ligne : http://www.sciencedirect.com/science/article/pii/S000888460900221X [article] Selection of an effective ASR-prevention strategy for use with a highly reactive aggregate for the reconstruction of concrete structures at Mactaquac generating station [texte imprimé] / Sean Hayman, Auteur . - 2012 . - pp. 605–610.
