摘要： The present invention relates to a method for recycling waste water from a stainless steel slag treatment process wherein stainless steel slag is brought into contact with water, in particular to neutralize the free lime contained therein, thereby producing said waste water. This waste water contains heavy metals, including at least chromium, and has a pH higher than or equal to 11. In accordance with the invention, it is used as production water for manufacturing mortar and/or concrete. In this way, the heavy metals, which are dissolved in the waste water and thus readily available, become bound in the newly formed cement phases so that they are prevented from leaching. Moreover, it has been found that the workability of the fresh mortar or concrete and also the quality of the final mortar or concrete materials is not negatively affected by the use of this alkaline waste water and that an accelerated setting could be achieved during the first hours.

摘要： The present invention relates to a process for preparing, starting from a slag material, a filler for construction materials which contain bitumen or a hydraulic binding agent. The slag used to prepare the filler contains γ-dicalcium silicate. The process comprises the step of removing from the slag material a finer fraction formed by particles of a size between 0 and at least 0.75 mm so as to reduce the γ-dicalcium silicate content of the slag material; and the step of finely milling at least a portion of the remaining coarser fraction of the slag to obtain the filler. The invention also relates to the obtained filler, to the use thereof for preparing construction materials and to concrete or mortar compositions and asphalt compositions containing the filler. By removing the finer fraction from the slag material, a filler is obtained which has a considerably lower water content so that it becomes suitable for use in asphalt or concrete or mortar compositions, in particular in self-compacting concrete compositions.

摘要： The present invention relates to a method for purifying highly alkaline waste water from a stainless steel slag treatment process. This waste water contains between 0.5 and 5 mg/l of trivalent chromium (Cr(III)) and between 0.5 and 1.0 mg/l of molybdenum. To reduce the chromium and molybdenum content a trivalent iron is added to the waste water in the form of a water soluble ferric salt and the trivalent iron is allowed to co-precipitate with said chromium and molybdenum by lowering the pH of the waste water. It was found that by performing the co-precipitation at a pH of 3.5 to 5.7, both the chromium and the molybdenum content could be effectively reduced to a level of less than 0.5 mg/l, and this without having to provide large amounts of trivalent iron in the waste water, without having to repeat the purification process for several times, without having to add sulphide to the waste water, and without having to lower and raise the pH of the waste water for more than one time.

摘要： The invention concerns a method of treating an alkaline granular carbonatable material which contains aluminium metal and which has in particular a pH of at least 10. The method comprises an oxidation step wherein at least a portion of said aluminium metal is oxidized by contact with moisture. The aluminium should be oxidized to avoid swelling problems when using the granular material as aggregate. In the method according to the invention this oxidation is accelerated by providing at least one oxidizing agent in said moisture, which oxidizing agent has a higher redox potential than the water contained in said moisture. The method further comprises a carbonation step wherein the granular carbonatable material is at least partially carbonated to lower the pH thereof. In this way the formation of ettringite, which may also release aluminium ions which causing further swelling problems, can be avoided in the granular material or any ettringite present therein can be destabilized.
