| Abstract: | Effect of sulfonated melamine type(SM) and polycarboxylate type(HC) water-reducing agents on water-reducing rates,setting time,strength,crystal growth habit and crystal morphology of flue gas desulphurization gypsum was analyzed.The results show that the water-reducing rate of flue gas desulphurization gypsum is improved,the setting time is extended,the block strength is changed,and the plaster hardened pore structure is improved by adding water-reducing agents. |
