From failure to recovery: CFRP strengthening of a near-collapse reinforced concrete wastewater structure with root cause diagnosis, failure mechanisms, and structural implications under aggressive environmental conditions
July 3, 2026 1:31 pm Reinforced concrete structures in wastewater treatment plants (WWTPs) operate under uniquely aggressive conditions, including biogenic sulphuric acid attack, sustained moisture, elevated temperatures, and partial submergence. Although Fiber Reinforced Polymer (FRP) strengthening is well established for bridges and other concrete infrastructure, its application within WWTPs raises concerns regarding bond durability and...Read More
