Service life prediction of underground concrete pipes subjected to corrosion

Concrete corrosion due to hydrogen sulfide attack is an inevitable prejudicious process in concrete sewer pipelines. A high rate of maintenance and repair costs and catastrophic consequences of a major sewer pipeline collapse lead asset managers to search for reliable methods for risk assessment and service life prediction of sewer systems. Furthermore, safety and risk assessment is gradually becoming a requirement for the design of new concrete sewers and for inspection, rehabilitation, upgrading, replacement, and demolition decisions of aging and deteriorated of concrete pipes.
