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 measurementsof equilibrium RH of concrete core specimens has beendemonstrated. It seems to be more accurate method compared toRH sensors since higher measurement values are obtained.Furthermore, the time of a single measurement is reduced andthis method can be applied even if a limited sample amount isavailable.
