Abstract

Cette invention concerne un béton à durcissement rapide. Ce béton, produit à partir de ciment Portland modifié ayant un temps de prise retardé, contient des composés polyhydroxy-aliphatiques solubles dans l'eau qui peuvent renfermer des groupes carboxyle sous forme de leur sel soluble dans l'eau, et une résine soluble dans l'eau, modifiée par un amino-acide aliphatique sous forme de son sel soluble dans l'eau, à base d'amino-s-triazine. Le rapport molaire formaldéhyde/amino-s-triazine/amino-acide est de (1,5 - 6) : 1 : (0,15 - 1). Il peut aussi renfermer des plastifiants et (ou) des agents formant des micropores d'air occlus. Ce béton présente un temps de prise permettant une bonne ouvrabilité, mais un durcissement rapide.
