Abstract

La présente invention concerne un procédé de conditionnement de déchets à base de borates et sels alcalins par immobilisation dans une matrice de cimentation dans lequel on mélange les dits déchets à des réactifs conduisant à un ciment de phosphate de zinc et/ou de phosphate de calcium, les dits réactifs comprenant de d'acide phosphorique H3PO4 dans de l'eau et ZnO pour le ciment de phosphate de zinc et CaO pour le ciment de phosphate de calcium. La présente invention concerne également une matrice cimentaire comprenant des déchets à base de borates et sels alcalins obtenue par un procédé de conditionnement selon l'invention.
