Degradation mechanisms of bio-enhanced geopolymers for acid-resistant sewer infrastructure

The long-term deterioration of sewer infrastructure in acidic environments presents a significant challenge for water utilities, as traditional cementitious materials tend to degrade rapidly when exposed to biogenic and industrial acids. To address this, this study investigates the durability of fly ash-based geopo...

Durability assessment of bio-modified geopolymer concrete in simulated sewage environments

Sewer infrastructure worldwide is ageing beyond its designed lifespan, rendering it increasingly vulnerable to biogenic sulphuric acid corrosion, cracking, and structural collapse. Geopolymer concrete represents a promising sustainable alternative to ordinary Portland cement in such aggressive environments; however, it...
