Application of Microwave Impulse Method for Measuring Moisture Profiles in Building Materials
Original language description
The moisture profiles were determined using a common capillary suction 1-D experiment in the horizontal position, lateral sides of specimens were water and vapor-proof insulated. Scanning by microwave impulse moisture meter along the specimen was done every 10 mm. The calibration curve was determined after the last scanning, when the moisture penetration front was at about one half of the length of the specimen, using this last scanning and the standard gravimetric method after cutting the specimen into10 mm wide pieces. The calibration curve presents the moisture content in building material in dependence on permittivity of this measured material. The permittivity of measured material was calculated on the basis of measuring the time difference , where t2 is the travel time of the impulse to pass the thickness of measured specimen and t1 the respective travel time in the air. The moisture profiles were then calculated from the calibration curve. The measurements were done at 25 C .
