Abstract

The invention discloses a glued stone gel material taking ferrosilicomanganese slag as the main raw material, which belongs to the technical field of building material. The glued stone gel material adopts the raw materials of ferrosilicomanganese slag, cement clinker, gypsum, burnt coal waste residue and a rock forming agent. The raw materials have the following weight percentage: 60 to 90 percent of ferrosilicomanganese slag, 0 to 30 percent of cement clinker, 2 to 10 percent of gypsum, 0 to 30 percent of burnt coal waste residue, and 0.5 to 10 percent of rocking forming agent. The ferrosilicomanganese slag is taken as the main raw material to produce the glued stone gel material, thereby not only making use of solid wastes, but also saving energy resources and protecting the environment. Simultaneously, the material has better performance than the ordinary Portland cement.
