The appropriate flux percentage for fired brick was found by adding different proportions of fluxes to lower the sintering temperature of vitrification. This study used the full factorial method to conduct experiment planning by adding different proportions of fluxes to perform the sintering and test the basic performance. In this study, the sintered materials were divided into five types: without added flux, added NaOH, Na2CO3, H3BO3, and CaCO3. Under sintering at different temperatures, the differences between and the impacts of each type of added fluxes were further compared to explore the mechanical performance and the basic properties of the sintered materials, and then through multivariate regression analysis, the optimal shape-forming variables were thereby found in hope of producing a lightweight brick that has the superior properties of certain strength, carbon reduction, and is lightweight as well as be able to provide another development direction for the sediment treatment.
