英文摘要In this study, a new low-carbon cementitious material named ECGF was prepared by using electrolytic manganese residue (EMR), carbide slag (CS), ground granulated blast-furnace slag (GGBS), and fly ash (FA) as raw materials. A series of tests including compressive strength, microstructure, toxicity leaching, and carbon emission calculation were performed to evaluate the optimum mix of ECGF, micro-mechanism, and environmental risk. The results show that the multi component interactions of EMR, CS, GGBS and FA determined the bonding strength gaining of ECGF. The optimal mass ratio of EMR, CS, GGBS, and FA was found to be 9:1:12:3, and the corresponding compressive strength of 28-day ECGF could reach 55.2 MPa, which was much higher than that of ordinary Portland cement (OPC) with the same water-to-binder ratio. The active sulfate ions in EMR, under alkaline conditions, activate the reactivity of GGBS and FA, promoting the formation of ettringite and C-S-H gel, thereby enhancing the compressive strength of the cementitious system. The leaching test and carbon emission calculation showed that the heavy metal and ammonium nitrogen content leached from ECGF were below the standard requirements, and CO2 emissions were lower than those of OPC, exhibiting good environmental performances. The key findings of this study provide a reference for the resource utilization of solid wastes and the development of all-solid wastes based low-carbon cementitious materials.
