The Concrete Degradation Caused by Ammonium Chloride Present in Coke Wastewater

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

NH4+ and Cl− ions are present in coke sewage and are suspected of causing devastating concrete destruction of wastewater tanks. The corrosive immersion in NH4Cl water solution of hardened pastes made from 3 different cements was performed. SEM and XRD analyses were used to determine the depth of the attack and trace the microstructural and crystalline phase evolutions. The main effect was revealed to be high porosity near the external surface and at different locations of damage fronts. Thanks to the biggest portlandite content, hardened cement paste of CEM I proved to be the most durable. CEM III underwent the slowest changes, but to the greatest extent.
