Sulfate Corrosion of MKG

The durability of geopolymers in sulfate-rich environments is a critical factor for their utilization in marine and salty area. This chapter explores the impact of the Si/Al ratio, a significant compositional parameter of MKG, on its resilience when exposed to sodium and magnesium sulfate solutions. Additionally, this study thoroughly investigates the stability of MKG mortars’ chemical, physical, and mechanical properties over the course of 180 days by evaluating a number of factors, including appearance, mass, dimensions, strength, microstructure, and chemical composition, while subjected to the immersion effects of both sodium sulfate and magnesium sulfate solutions.
