Waste stabilisation using hydraulic binder
In a waste stabilisation process employing a hydraulic binder, a nitrate or nitrite ion-containing material is added during preparation of the mortar based on waste, hydraulic binder and water. Preferably, the added material is selected from nitrates and nitrites of Fe, Al, Na, K, Ca and Mg and dilu...

| description | In a waste stabilisation process employing a hydraulic binder, a nitrate or nitrite ion-containing material is added during preparation of the mortar based on waste, hydraulic binder and water. Preferably, the added material is selected from nitrates and nitrites of Fe, Al, Na, K, Ca and Mg and dilute nitric acid and is added in amount 1.5-60 (preferably 3.5-30) wt. parts (expressed as nitrate or nitrite ions) per 1000 wt. parts of waste. Also claimed is a mortar which is based on hydraulic binder, waste and water and which additionally contains a nitrate or nitrite ion-containing material.
L'invention concerne un procédé de stabilisation de déchets à l'aide d'un liant hydraulique. Le procédé se caractérise en ce que, lors de la préparation du mortier à base de déchets du liant hydraulique et de l'eau, on ajoute un matériau contenant des ions nitrate ou nitrite.par. |
