【 摘 要 】

A new type of plastering gypsum which has good operability was prepared from calcined desulphurization gypsum, ground steel slag and appropriate additives. The proper material ratio is: calcined desulphurization gypsum 95%, ground steel slag 4.5%, and water-retaining additive 0.5%. The product meets the requirements of GB/T 28627-2012. The effects of energy saving and emission reduction of this product were analysed. Compared with the common cement-based or lime-based materials, it has the advantages of better volume stability, lower application cost and less carbon emission.
