Abstract Geopolymer concrete has received widespread attention due to its low-carbon and high corrosion resistant characteristics. In this work, geopolymer concrete beams were prepared using slag as a main precursor, mixed with fly ash and ceramic powder, and their flexural performance under load and chloride attack was analyzed. The changes in deflection, cracks, strains, and chloride ion penetration were investigated by varying the load holding and attack days. The results show that the mechanical property change curves under coupling have high similarity with the pattern of ordinary portland cement concrete and the flexural and erosion resistance is higher than that of ordinary portland cement concrete of the same strength. The test results provide data support for the application of geopolymers in structural engineering.

Key words： geopolymer concrete loading chloride attack coupling effect deflection crack
