Abstract

L'invention concerne un procédé de construction mettant en oeuvre du béton appliqué à une enceinte de procédé intégral dans laquelle sont réalisés des procédés complets ou des parties de procédés de distillation et/ou de séparation à effets multiples, à empilement vertical, à grande échelle, et en particulier des procédés de dessalement par distillation à multiples effets, à empilement vertical. Selon l'invention, une telle enceinte en béton de procédé intégral est divisée au moins en deux zones différentes de procédé, chaque zone de procédé se réfère à un degré différent de sévérité d'attaque dans les conditions de procédé respectives. Dans chacune de ces zones, la partie de l'enceinte qui est en contact direct avec les conditions de procédé est construite au moyen d'un mélange de béton correspondant aux conditions de procédé de cette zone. Ainsi, l'enceinte résultante précontrainte de procédé intégral, construite au moyen de procédé à couches multiples et/ou à segments multiples ou au moyen de coffrage sautant, glissant, grimpant ou du même type, ce qui la dote fonctionnellement d'au moins deux mélanges de béton différents possédant des propriétés notablement différentes, avec par conséquent des coûts différents, l'ensemble résultant en un procédé de construction économique et durable.
