Definitions

  • epoxy resin-based or acrylic resin-based resin compositions containing silica sand, sand, and the like have been mainly used.
  • Conventional acrylic resin mortars have problems in terms of adhesive strength, compressive strength, bending strength, or the complexity of preparation for painting. For example, in the case of concrete, especially new concrete, the curing period after casting is long, and it is necessary to sufficiently dry the moisture contained in the concrete, and strong adhesion and hardening could not be achieved.
  • acryl-based resin compositions often cannot be applied satisfactorily if they are damp during use. Furthermore, they had strong odor and toxicity, and had many problems in construction safety. There are many problems with the conventional resin composition in terms of water penetration, water absorption, freezing and thawing, roughness coefficient, and the like, and none of them can sufficiently cope with preventing corrosion of iron, preventing deterioration of concrete, and waterproofing.

Abstract

Une préparation de résine composite pouvant être appliquée même sur des zones humides, possédant, entre autres, une excellente imperméabilité, durcit rapidement, ne se fluidifie pas et ne gauchit pas une fois appliquée. On produit ladite préparation en mélangeant au moins un agrégat pulvérulent, un matériau hydraulique, une résine époxy synthétique et un durcisseur de résine. Juste avant de l'utiliser, on mélange la résine époxy au durcisseur de résine, dans des proportions données. L'agrégat pulvérulent contient des fins cristaux grenats et présente un diamètre de particule moyen de 5 à 1 200 νm. Le matériau hydraulique est un ciment hydraulique comprenant de l'oxyde de silicium, de l'oxyde d'aluminium, de l'oxyde ferrique, de l'oxyde de calcium, de l'oxyde de magnésium et de l'oxyde de sodium, dans des proportions données. La résine époxy synthétique contient du talc, en dose donnée, à base de résine époxy modifiée. Le durcisseur de résine contient du talc en quantité donnée, à base de sel d'acide aminé et de sel d'acide d'amide.
