Method for producing xonotlite by taking pulverized fuel ash as raw material
2013
The invention discloses a method for producing xonotlite by taking pulverized fuel ash as a raw material. The method comprises the following steps: with the pulverized fuel ash as a raw material, preparing a refined desilicification solution by adopting an alkali dissolution method, and mixing the refined desilicification solution with a refined lime milk solution to carry out a hydro-thermal synthesis reaction to obtain the xonotlite. According to the method for producing the xonotlite by taking the pulverized fuel ash as the raw material, the pulverized fuel ash is used as the main raw material and is effectively subjected to desilicification by using dilute alkali liquor, so that the dosage of the alkali liquor is reduced, and meanwhile, exploitation and utilization of ores, such as silica sand, kieselguhr and the like are greatly reduced.
