Study on Influence of Properties of the Gypsums on Property of α-Hemihydrate Gypsum

Yang Lin Zhou Jie Zhang Bing Cao Jianxin(School of Chemistry and Chemical Engineering,Guizhou University,Guiyang,Guizhou 550025)  
By comparing chemical composition,microstructure and solubility of different gypsums,the influence of the properties of the gypsums on the property and morphology of α-Hemihydrate gypsum was studied.The experimental results showed that the properties of α-Hemihydrate gypsum,such as setting time,water demand,strength and so on,were very different under steaming method using various gypsums,including natural gypsum(NG),phosphogypsum(PG) and chemical gypsum(CG).The strength of the sample made of NG was the highest,and met the need of JC/T 2038-2010 α-hemihydrate gypsum plaster α30.PG had many impurities,and the crystal particle of PG was smaller,which could reduce the strength of the sample.The crystal particle of CG is the smallest,and the property of the sample is the worst.
