Coal gasification coarse slag lixivium, preparation method and application thereof, and geopolymer material
The invention belongs to the technical field of alkali activators, and particularly relates to a coal gasification coarse slag leachate, a preparation method and application thereof, and a geopolymer material. The invention provides a coal gasification coarse slag lixivium, the lixivium comprises Na2SiO3, CASH gel and active components, and the active components comprise Ca (OH) 2 and NaOH; the modulus of the leachate is 0.7-1.0, the density is 1.05-1.15 g/cm < 3 >, the Baume degree Be is 10-20, the content of sodium oxide is 5-6 wt%, and the content of silicon dioxide is 3-6 wt%. The coal gasification coarse slag leachate provided by the invention can directly replace an alkali activator to prepare an alkali-activated material, the prepared alkali-activated material has higher activity and lower ignition loss, the alkali-activated material has wide application, and the utilization rate of the coal gasification coarse slag is increased.
本发明属于碱激发剂技术领域，具体涉及一种煤气化粗渣浸出液及其制备方法和应用、地质聚合物材料。本发明提供了一种煤气化粗渣浸出液，所述浸出液中包括Na2SiO3、CASH凝胶和活性组分，所述活性组分包括Ca(OH)2和NaOH；所述浸出液模数为0.7～1.0，密度为1.05～1.15g/cm3，波美度Be为10～20，氧化钠含量为5～6wt％，二氧化硅含量为3～6wt％。本发明提供的煤气化粗渣浸出液能够直接替换碱激发剂制备碱激发材料，制备得到的碱激发材料具有较高的活性和较低的烧失量，所述碱激发材料具有广泛的应用，提高了煤气化粗渣的利用率。
