TECHNOLOGIE DU B%u00c9TONwww.cpi-worldwide.com PBI %u2013 Pr%u00e9fa B%u00e9ton International %u2013 3 | 2026 39Valoriser les d%u00e9chets issus du lavage des camions-malaxeurs pour g%u00e9n%u00e9rer des mati%u00e8res premi%u00e8res: Sven-Henrik Norman, chef de produit de la ligne Re-Con, a r%u00e9cemment %u00e9t%u00e9 interview%u00e9 par un repr%u00e9sentant de Svensk Betong, la principale association su%u00e9doise des professionnels du b%u00e9ton et de la pr%u00e9fabrication. M. Norman a expliqu%u00e9 les avantages du syst%u00e8me de lavage %u00e0 sec Re-Con, notamment les %u00e9conomies potentielles qu%u2019il repr%u00e9sente pour les producteurs de b%u00e9ton pr%u00eat %u00e0 l%u2019emploi. En effet, compar%u00e9 aux techniques de lavage courantes, Re-Con %u00e9limine la n%u00e9cessit%u00e9 de mise en d%u00e9charge des boues de lavage, et r%u00e9duit consid%u00e9rablement la consommation d%u2019eau, les salissures et les risques de pollution.Comment fonctionne concr%u00e8tement le lavage %u00e0 sec dans le tambour d%u2019un camion-malaxeur %u00e0 b%u00e9ton? %u2013 On commence par ajouter environ deux tonnes de ballast issu de b%u00e9tons recycl%u00e9s. Ce ballast est tr%u00e8s absorbant car il contient de nombreux restes de ciment durcis, ce qui est id%u00e9al pour lier les r%u00e9sidus de ciment frais dans le tambour vide du camion-toupie.Quels sont les avantages environnementaux du lavage %u00e0 sec par rapport au nettoyage traditionnel? %u2013 Gr%u00e2ce %u00e0 cette technique, il est possible d%u2019absorber jusqu%u2019%u00e0 80% des restes de ciment pr%u00e9sents dans un malaxeur vide, qui viennent se coller au ballast de lavage sec. Ainsi, si le producteur de b%u00e9ton souhaite tout de m%u00eame effectuer un rin%u00e7age rapide %u00e0 l%u2019eau, la proportion de mati%u00e8res potentiellement dangereuses pr%u00e9sentes dans les boues liquides est consid%u00e9rablement r%u00e9duite.En revanche, s%u2019il pr%u00e9f%u00e8re utiliser la m%u00e9thode de lavage traditionnelle, qui utilise uniquement de l%u2019eau, le flux de d%u00e9chets est beaucoup plus important et potentiellement plus dangereux qu%u2019avec le lavage %u00e0 sec. Le lavage %u00e0 l%u2019eau produit toujours des r%u00e9sidus de ciment qui peuvent contenir une quantit%u00e9 importante de ciment, ce qui pr%u00e9sente un risque de dissolution du chrome, notamment du chrome hexavalent. Tous ces d%u00e9chets sont ensuite transport%u00e9s dans un bassin, o%u00f9 leur s%u00e9dimentation n%u00e9cessitera beaucoup de temps. En outre, il est beaucoup plus difficile de recycler l%u2019eau pour la r%u00e9introduire dans le processus de production de b%u00e9ton.Comment cette technologie contribue-t-elle %u00e0 r%u00e9duire le besoin de mise en d%u00e9charge et la consommation d%u2019eau? %u2013 D%u00e8s lors qu%u2019il a %u00e9t%u00e9 possible de lier les r%u00e9sidus de ciment provenant du malaxeur, et de les absorber avec le ballast de lavage %u00e0 sec pour cr%u00e9er encore plus de ballast, le probl%u00e8me des boues liquides est r%u00e9solu. Au lieu d%u2019utiliser une m%u00e9thode de lavage fortement consommatrice d%u2019eau qui g%u00e9n%u00e8re des effluents liquides comme les boues, nous obtenons un granulat sec qui peut %u00eatre r%u00e9utilis%u00e9 pour la production de b%u00e9ton, et qui permet %u00e9galement de mieux capter le dioxyde de carbone. Les %u00e9conomies r%u00e9alis%u00e9es et les avantages environnementaux d%u00e9coulent d%u2019un double b%u00e9n%u00e9fice: la r%u00e9duction du volume de d%u00e9chets mis en d%u00e9charge et la production simultan%u00e9e de granulats secondaires qui se substituent aux mati%u00e8res premi%u00e8res primaires dans la production de b%u00e9ton. nAvantages de la technologie de lavage %u00e0 sec pour l%u2019environnementMapei SpA, Milan, ItalieAUTRES INFORMATIONSMapei SpAVia Cafiero, 22, 20158 Milan, ItalieT +39 02 37673 1mapei.com, mapei@mapei.itwww.cpi-worldwide.comCONCRETE TECHNOLOGY CONCRETE TECHNOLOGY96 CPI %u2013 Concrete Plant International %u2013 2 | 2025 www.cpi-worldwide.com www.cpi-worldwide.com CPI %u2013 Concrete Plant International %u2013 2 | 2025 97Kraft Curing Systems is proud to be a technology leader in concrete curing.
