Reinforced concrete is widely used in large infrastructures tunnels, garages, bridges, etc.) and in many public and private buildings. However, the service life of reinforced concrete structures is often limited due to corrosion of the steel reinforcement. Concrete structures suffering from corrosion have to be repaired in order to reach their expected service life but there is currently a lack of knowledge to determine the right time of repair. This results in: -Foregone revenues due to a too early repair of the structure -Compromised safety if repair is not timely performed which ultimately endanger human life With our solution, we aim at obtaining continuous reliable corrosion diagnosis and forecast, which can be used both for structures built with traditional Portland Cement but also containing new blended cements. With our solution, we can help our customers selecting the right type of repair, for the right structure at the right time. Our solution enables decreasing the number of structures needing repair simultaneously and thus helps diminishing corrosion costs while ensuring safety.
