In this study, reference the method of preparing cement sand to produce geopolymer, using Electrolytic Manganese Residue(EMR), fly ash, magnesium slag (with boric acid), sodium silicate, sand, calcined kaolin as the main raw materials, focus on the study of using electrolytic manganese residue to produce Geopolymeric cement. Finally, through a series of comparison, we find out the best recipe of Geopolymer preparation, and the best ratio of each raw material is 80% EMR, 10% magnesium slag, 10% fly ash. In this way, the Geopolymer has the best mechanical properties.
