Abstract

Because of the strong alkalinity and large amount of heavy metals in red mud, many countries have paid more attention to red mud. According to the traditional treatment method, an innovative scheme is proposed in this paper, which uses red mud (RM), ground granulated blastfurnace slag (GGBS), fly ash (FA) and coal gangue (CG) to produce a new type of low carbon, environmental protection and wide application scenarios geoppolymer (RSF + C). In this paper, the simple centroid design method is used to optimize the ratio of terpolymer, and the mechanical properties of RGF + Cs are analyzed by uniaxial compression. The strength formation mechanism of RGF + Cs was revealed by TG-DTG and SEM-EDS techniques. The results show that the optimal UCS of RSF + Cs is 5.25MPa. RM provides a positive alkaline environment for GGBS and FA, but excess RM can cause UCS to decline. A large amount of C-A-S-H and C-S-H gels were found in the samples by microscopic analysis.
