The influence of cement addition on moisture variation in the restoration of lime base brick walls

Moisture data in wall structures is essential for assessing damage and preventive conservation in tangible cultural heritage. Moisture infiltration accelerates wall deterioration, particularly in Taiwan’s humid climate, leading to instability and high restoration costs. This study examines different cement proportions in mortar on semi-outdoor brick specimens, using infrared thermal imaging and a high-frequency moisture meter for non-invasive moisture assessment.

The findings reveal that a 5% cement proportion effectively reduces moisture effects on walls. The study provides restoration recommendations and suggests a rapid moisture inspection method using thermal imaging and moisture meters.
