| titleOfInvention | It is a kind of efficiently to utilize the low-heat cement of industrial waste gypsum |
| abstract | The low-heat cement of industrial waste gypsum can be efficiently utilized the invention discloses a kind of, the cement is by certain mass proportioning cement slurry to be made by raw material of lime stone, bauxite, clay, sulfate slag, fluorite, barium slag and treated industrial waste gypsum, and well mixed and grinding into calcining after raw meal powder at a certain temperature；Industrial waste gypsum and conditioning agent are added in the clinker burnt till, so that product is made.Utilization rate of the industrial waste gypsum in manufacture of cement greatly improved in the present invention；It is formulated in the product formed and reduces C 3 S contents, improve C 2 S contents, so that the heat of hydration is relatively low, simultaneously because introducing early-strength mineral sulphoaluminate phase, along with appropriate industrial waste gypsum and conditioning agent promote its aquation, with preferable early strength, the low defect of general low-heat cement early strength is overcome, the application of low-heat cement has been widened. |
