Soundness evaluation method for concrete structures based on the data obtained from decommissioning Hamaoka nuclear power plant Part 6: Measurement of equilibrium relative humidity

摘要

The applicability of a water activity meter for measurementsrnof equilibrium RH of concrete core specimens has beenrndemonstrated. It seems to be more accurate method compared tornRH sensors since higher measurement values are obtained.rnFurthermore, the time of a single measurement is reduced andrnthis method can be applied even if a limited sample amount isrnavailable.
