CA 2202281

A curable composition comprising (A) a slag composition containing 0-37 wt.% of CaO, 23-90 wt.% of SiO2, 0-40 wt.% of A12O3, and at least either 0.1-10 wt.% of halogen or 0.1-50 wt.% of at least one member selected among iron oxides, alkalies, phosphorus, titanium oxides, manganese oxides and magnesium oxide, and (B) an alkaline stimulant; and cured articles made by mixing the composition with water. The articles have the properties suitable for use as, e.g., various concrete materials, thus contributing to the utilization of waste incineration ash or sewage as resources.

L'invention concerne une composition durcissable, qui comprend (A) une composition de laitier comportant en poids entre 0 et 37 % de CaO, entre 23 et 90 % de SiO¿2?, entre 0 et 40 % de A1¿2?O¿3? et au moins entre 0,1 et 10 % d'halogène ou entre 0,1 et 50 % d'au moins un constituant choisi parmi les oxydes de fer, les alcalis, le phosphore, les oxydes de titane, les oxydes de manganèse et l'oxyde de magnésium, et qui comprend aussi (B) un agent de stimulation alcalin. On décrit par ailleurs des articles durcis obtenus par mélange de la composition avec de l'eau. De part leurs propriétés, ces articles peuvent être utilisés par exemple comme composant divers du béton, l'élaboration contribuant ainsi à employer comme ressources les cendres de déchets incinérés ou les eaux usées.
