Water-resistant Modification of Desulphurization Gypsum block
A high performance water resistance agent KD-3 prepared from OPC cement,fly ash,slag and additives was used for the modification of hemi-hydrate desulphurization gypsum.Various factors on gypsum block were investigated.The prepared gypsum block possesses excellent water-resistance,good operating property and high mechanical strength.The optimized results was obtained: calcined gypsum 74.9%,KD-3 25%,retarder 0.1%,curing temperature 60℃ and curing time 16h.
