Experimental study on using electrolytic manganese slag as a cement retarder instead of industrial gypsum
Electrolytic manganese slag is a common industrial solid waste in the electrolytic manganese processing industry.The cur-rent disposal methods are mainly underground landfill or open-air storage,and its large amount of disorderly stacking brings serious en-vironmental problems.With the implementation of the new environmental protection law,local governments and electrolytic manganese processing enterprises are facing more severe environmental forms,and the reasonable disposal of electrolytic manganese slag has be-come an important core issue facing local economic and social development.The characteristics of electrolytic manganese slag were an-alyzed and studied using instruments and equipment such as the German Brooke elemental analyzer.By using electrolytic manganese slag in combination with industrial gypsum as a cement retarder,the feasibility of resource utilization of electrolytic manganese slag in cement production was explored,which has good environmental and economic benefits.It has certain reference value for the effective disposal of electrolytic manganese slag.
