The influence of hygroscopic humidity from salts on moisture measurements in the case of the ‘ Boskapel ’ chapel in Imde-Meise , Belgium

Abstract

When investigating moisture in building materials it is important to study both the actual and hygroscopic moisture contents (AMC; HMC) as well as the salt content. The presence of hygroscopic salts can often lead to misinterpretation of the moisture content and source. A high HMC can often be held responsible for a high AMC and result in an incorrect diagnosis and non-adapted treatment. We present a multi technique approach to investigate the presence of moisture and salts in the interior of a chapel in Imde-Meise , Belgium to provide advice for the optimal conservation. Peer-review under the responsibility of the organizing committee of the ICMB21.
