Extrudable reactive powder concretes / Pierre Mounanga in European journal of environmental and civil engineering, Vol. 16 Supplément N° 1 (Juin 2012) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 Supplément N° 1 (Juin 2012) . - pp. s99-s114 Titre : Extrudable reactive powder concretes : Hydration, shrinkage and transfer properties Type de document : texte imprimé Auteurs : Pierre Mounanga, Auteur ; Khalid Cherkaoui, Auteur ; Abdelhafid Khelidj, Auteur Année de publication : 2012 Article en page(s) : pp. s99-s114 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Reactive  powder  concrete  Extrusion  Hydration  Shrinkage  Durability Résumé : The behaviour of five reactive powder concretes (RPC), with four of them being extrudable, has been studied from the first minutes up to more than 90 days. The extrusion force, hydration rate, free autogenous shrinkage at early age, mechanical properties and durability parameters were measured. The performance analysis showed the benefits of a partial substitution of silica fume with crushed quartz on the RPC properties. The cost/performances analysis highlighted that the main advantage of using RPC lies in their potential of durability, which is 10 to 100 times higher than that of ordinary or high-performance concretes, according to the property considered.
