Abstract

Procédé pour préparer des fibres synthétiques minérales, utilisables pour le renforcement de produits du ciment. Il consiste à réduire la longueur des fibres de laine minérale par broyage par choc, par exemple dans un broyeur à percussion, à purifier par voie humide la substance fibreuse ainsi formée, par dispersion dans un milieu aqueux, et à récupérer les fibres ainsi purifiées. Les produits ainsi obtenus confèrent aux produits en ciment qu'ils renforcent un module de rupture nettement plus élevé.Process for preparing synthetic mineral fibers, usable for the reinforcement of cement products. It consists in reducing the length of the mineral wool fibers by impact crushing, for example in an impact crusher, in wet purifying the fibrous substance thus formed, by dispersion in an aqueous medium, and in recovering the fibers thus purified. The products thus obtained give the cement products they reinforce a markedly higher modulus of rupture.
