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.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a gelatinous cementitious material with silicomanganese ferroalloy slag as the main raw material. Background technique [0002] As a deoxidizer and alloy additive for steelmaking, ferroalloy is one of the indispensable raw materials for steel production. At present, China's ferroalloy production capacity has reached 12 million tons per year, and the production capacity is 19 million tons including reconstruction projects. There are more than 4,000 manufacturers. The output in 2004 was 8.65 million tons. According to the ratio of 1:1, 800 tons of waste residue can be produced. tons. For a long time, ferroalloy slag has been discharged as solid waste, occupying a large amount of land, destroying surface vegetation and landscapes, aggravating soil erosion, dust noise, polluting water sources, etc., causing huge damage to the social environment and ecological environment,...
