Abstract
Microbial-induced corrosion of ordinary Portland cement concrete due to its low biogenic acid resistance is still a global concern, requiring scientists to develop sustainable alternative binders. Accordingly, this study investigates the biogenic acid resistance of alkali-activated glass powder/GGBS mortars with various amounts of calcium aluminate cement (CAC) to replace GGBS while fixing the glass powder (GP) at 75% by mass. The results revealed that incorporating CAC to replace GGBS at 15% in alkali-activated cement (AAC) mortars improved the resistance to microbial-induced corrosion due to incorporating more Al into the AAC gels and can be proposed as a sewer repairing material.
