The massive stockpiling of electrolytic manganese residue (EMR) has caused serious environmental pollution. In this study, EMR, coal gangue (CG), and fly ash (FA) were used as raw materials to obtain the optimal mix ratio based on Design-Expert mixture design. effects activator modulus, liquid–solid (L/S) ratio, curing temperature mechanical properties geopolymers investigated. results showed that compressive strength prepared geopolymer was 12.0 MPa, 28d leaching Mn 0.123 mg/L under conditions EMR:CG:FA = 0.43:0.34:0.23, L/S 0.9, a 60 °C, time 24 h. This indicates is an environmentally friendly material with high strength. mineral composition mainly hydrated calcium silicate gel. addition, more stable new phase, MnSiO3, generated. Fourier transform infrared (FTIR) spectrogram peak at 1100 m−1 shifted 1112 cm−1, which indicated geopolymerization reaction had occurred. Through scanning electron microscopy (SEM) energy dispersive spectrum (EDS) analysis, it identified produced large amount amorphous gelatinous substances relatively dense structure, major elements being oxygen, silicon, aluminum, calcium, sodium.
