Preparation method of tungsten tailing-based geopolymer
The invention relates to a preparation technology of building materials, in particular to a preparation method of a tungsten tailing-based geopolymer. The geopolymer is prepared by taking tungsten tailings and fly ash as main raw materials in a water adding integrated manner. The method comprises the following steps of: respectively carrying out roasting activation treatment on Na2CO3, tungsten tailings and fly ash to respectively generate roasting products taking Na6.8 (Al6.3Si9.7O32) with better activity as a main phase (Na6.8 (Al6.3Si9.7O32) is dissolved in water to form simple silicate and aluminate), grinding and well mixing the two roasting products, directly adding water, mixing and stirring, and carrying out sample preparation and maintenance to obtain the tungsten tailing-based geopolymer with high mechanical properties. The lowest compressive strength of the geopolymer can reach 110 MPa after the geopolymer is maintained for 28 days. The preparation process is safer, simpler, more convenient and high in operability.
本发明涉及建筑材料的制备技术，具体是一种钨尾矿基地聚物的制备方法。本发明采用“加水一体化”的方式，以钨尾矿和粉煤灰为主要原料制备地聚物。将Na2CO3分别与钨尾矿和粉煤灰进行焙烧活化处理，分别生成以活性较好的Na6.8(Al6.3Si9.7O32)为主要物相的焙烧产物(其中的Na6.8(Al6.3Si9.7O32)溶于水形成简单的硅酸盐与铝酸盐)，将两种焙烧产物研磨后混合均匀，直接加水混合搅拌，通过制样养护制备具有较高力学性能的钨尾矿基地聚物，本发明的地聚物抗压强度在养护28天后，最低抗压强度可达110MPa。本发明的制备过程更加安全、简单、方便、可操作性强。
