MONITORING OF MOISTURE IN RENDERED AUTOCLAVED AERATED CONCRETE WALL BY NAIL ELECTRODES

摘要

Continuous moisture monitoring of rendered autoclaved aerated concrete (AAC) with nail electrodes has been carried out within a research project investigating the long-term performance of external walls made of rendered AAC. The moisture content is continuously measured at different depths of the rendered AAC test blocks naturally exposed on a test rack and of the rendered AAC test panels mounted at the field exposure station built within the EUREKA-project E 2116 DurAAC. The data and results obtained so far show that it is possible to assess the actual in-service moisture performance of different rendering systems on AAC on the basis of electrical measurements of moisture.
