Autoclaved aerated concrete (AAC) is a load bearing construction material, which has high heat insulation parameters. The most common problem for AAC heat insulation properties is the excessive moisture content in the AAC materials as well as its distribution throughout the cross section of the masonry elements. Therefore, the drying process of the AAC masonry constructions shall be monitored in order to avoid application of finishing layers on the construction before it has dried to the state it can reach the heat insulation parametres stated at the design stage. Electrical impedance spectrometry (EIS) is applied for monitoring of drying process of the masonry constructions and detection of moisture distribution throughout the cross section of AAC masonry constructions. This research describes monitoring of water infiltration in autoclaved aerated concrete masonry construction blocks by electrical impedance spectrometry.
