| 内容記述 | Biomass fly ash can serve as one of the precursors for producing geopolymer. The type of biomass fly ash, alkaline activator, and curing conditions all influence the mechanical properties of the geopolymer. The optimal M⁺ and AM values were found to be 11.5% and 0.75, respectively. SiO₂, Al₂O₃, and CaO content in biomass fly ash significantly affect the mechanical performance.Microorganisms can be used to develop self-healing geopolymers. Bacillus cohnii was employed as the microbial source, and high-calcium and low-calcium fly ashes were selected as additional calcium sources. Results demonstrated that high-calcium fly ash exhibited more positive effects. SEM-EDS analysis confirmed the formation of CaCO₃. Additionally, the presence of EPS was identified, which serves as a nucleation site for CaCO₃, thereby promoting self-healing. | |||||
