HA25/8mm - Sac hydrosoluble

Le béton sec HA25/8mm en sac hydrosoluble fabriqué par AYMAR S.A. est un béton sec à finition fine fourni dans un sac écologique qui se dissout en présence d'eau, laissant intactes les propriétés physiques et chimiques du béton.

Ce système offre des conditions de travail plus propres car il ne génère pas de poussière, plus sûres car il évite les blessures possibles lors de l'ouverture des sacs et l'inhalation de poussière, plus durables car il ne génère pas de déchets et plus rapides.

  • Domaine d'application
  • Mode d'emploi
  • Recommandations d'utilisation

Le béton sec HA25/8mm est un béton de qualité adapté aux travaux de construction généraux dans des environnements à exposition normale, à humidité élevée (XC2). Convient à tous les types de travaux de maçonnerie ; béton pour trottoirs, béton pour bordures, béton pour remplissage, béton imprimé, chapes polies... Particulièrement adapté aux applications où une finition fine est requise.

  • Préparation du support : Nettoyer et humidifier les supports avant l'application et attendre la disparition du film d'eau. Préparez le support avec un treillis approprié pour l'armature du béton.
  • Préparation du mélange: utilisez toujours de l'eau propre et courante. Mettez le sac dans la bétonnière (il n'est pas nécessaire de l'ouvrir). Ajoutez 3 à 3,5 litres d'eau par sac. Pétrir jusqu'à l'obtention d'une pâte homogène.
  • Application de l'échantillon: L'épaisseur minimale de l'application sera de 4 cm, permettant toujours un compactage complet de la masse. Une fois le mélange malaxé, il sera appliqué avant le début de la prise.
  • L'excès d'eau entraîne une diminution de la résistance.
  • Appliquer sur des supports présentant un certain degré d'absorption, d'humidité et une parfaite prise.
  • Ne pas appliquer à des températures inférieures à 5ºC ou supérieures à 35ºC.
  • Évitez le gel, les vents forts et l'exposition à un soleil intense pendant l'application.
  • L'ajout d'autres matériaux (additifs, ciment, etc.) peut modifier le comportement et les caractéristiques du produit.

Information

  • Composé d'agrégats de calcaire métamorphique concassé destinés à la construction, comme agrégats pour béton et mortiers (EN 12620 et EN 13139), de ciment CEM I - 42,5R (EN 197-1 et UNE 80601) et d'additifs organiques pour améliorer la résistance à la compression.
