Abstract
Nowadays important concrete infrastructure is increasingly being designed for long service life by modelling of degradation and probabilistic assessment of uncertainties, e.g. using the DuraCrete method. Although on paper a reliable and durable structure will result, it is the execution phase that can make or break the service life approach. Hence, testing of concrete for durability during the actual production is needed. This paper presents a validation study of a non-destructive production control and service life achievement of important cast in situ parts of the Green Heart Tunnel. Production control is based on Two Electrode Method testing, while validation consisted of measurements taken after one to three years on site and testing of cores using Rapid Chloride Migration testing. The results show that quality control by resistivity testing as exercised in this project was successful
