Durability evaluation of circulating fluidized bed fly ash-based geopolymer
View through CrossRef
To make full use of the circulating fluidized bed fly (CFB-FA), rich-water carbide slag was used as alkali-activator to promote the hydration of CFB-FA and prepare circulating fluidized bed fly-based geopolymer (CFB-FAG). The fundamental properties, mechanical properties, and acid alkali-resistance of CFB-FAG were investigated. The optimum content of CFB-FA is 25%. it indicates that CFB-FA can prepare the excellent properties of geopolymer without high-temperature heat treatment. The alkali resistance of CFB-FAG is better than that of acid resistance. Furthermore, the fatigue lifetime of CFB-FAG decreases by 20% after acid treatment. The achievement can help us make full use of the solid waste and achieve the goal of peak carbon dioxide emissions and carbon neutral.
