Outline of Final Research Achievements |
Three series of experimental tests were carried out. For the solid section, measurement depth of high-frequency capacitance sensor resulted increasing commensurately with distance of electrodes. For the void section, measurement span of high-frequency capacitance sensor resulted increasing commensurately with distance of electrodes, but not for the measurement depth. Observed value of high-frequency capacitance sensor with different distance of electrodes, was influenced by the width of void. Using of different distance of electrodes, observed values can derive a certain depth of void in mortar.
