Abstract

L'invention concerne une suspension aqueuse d'hydroxyde d'au moins un élément de transition sélectionné, dont le potentiel d'oxydo­ réduction est inférieur à celui du couple Cr072-/Cr042- (-0.12 V) ayant un pH compris entre 2 et 11, bornes exclues, pour réduire la teneur en chrome VI du ciment a une valeur au plus égale à 2 ppm, qui se caractérise en ce qu'elle comprend de 0,5 à 80% en poids de matiere seche d'hydroxyde d'au moins un element de transition rapporte à la quantité d'eau et en ce qu'elle est stabilisée par un agent de stabilisation hydrosoluble. Cette suspension permet de réduire la teneur de chrome VI des ciments a une valeur au plus égale à 2 ppm.
