METHOD FOR MEASURING MOISTURE CONTENT IN CONCRETE WITH SMALL STAINLESS STEEL ELECTRODES

Measuring sensors made of ceramic have been studied for measuring the moisture content of concrete. As a result, the moisture content distribution inside concrete has been clarified. Furthermore, a moisture content measuring sensor equipped with small stainless steel electrodes, measuring 0.7 mm in diameter and 20 mm in length, was developed for the current study to locally measure the moisture content distribution inside concrete, thereby examining the temperature, applied voltage, influence of metal near the electrodes, and the coefficient of variation of specific electrical resistance during the test.
