Method for preparing geopolymer by using chromium slag
The invention particularly relates to a method for preparing a geopolymer by using chromium slag, the method for preparing the geopolymer by using the chromium slag comprises the following steps: preparation of an alkali activator: adding sodium hydroxide into a water glass solution, stirring until the sodium hydroxide is completely dissolved into the water glass solution, sealing and cooling; pretreatment of the chromium slag: crushing the chromium slag and then sieving; and preparation of the geopolymer: uniformly mixing the crushed chromium slag with the micro powder, adding the alkali activator, uniformly stirring, pouring into a mold, carrying out vibration molding, maintaining, removing the mold, and maintaining at room temperature to obtain the geopolymer. According to the method for preparing the geopolymer by using the chromium slag, the chromium slag is subjected to building material treatment, the problem of consumption of the chromium slag is solved, the resource additional value of the chromium slag is improved, and zero emission and resource utilization of the chromium slag can be achieved through the building material utilization method.
本发明具体涉及一种利用铬渣制备地聚合物的方法，该利用铬渣制备地聚合物的方法，包括步骤：碱激发剂的配制：将氢氧化钠加入水玻璃溶液里，搅拌至氢氧化钠全部溶解到水玻璃溶液里，封存冷却；铬渣的预处理：将铬渣进行粉碎，再过筛；地聚合物的制备：将粉碎好的铬渣与微粉混合均匀，再加入碱激发剂，搅拌均匀后，倒入模具中震动成型，养护后拆模，室温养护即可得地聚合物。本发明利用铬渣制备地聚合物的方法，对铬渣进行建材化处理，解决了铬渣的消纳问题，提高铬渣的资源化附加值，建材化利用的方法可以实现铬渣的零排放和资源化。
