Abstract[Bearbeiten]

In historic masonry structures, rising damp is the main source of moisture and salt. Damage due to moisture and salts is augmented after archaeological research, where decay occurs before and after excavation. This study investigates the conservation of salt-damaged fired bricks dating back to the Roman period from the archaeological site Sagalassos through desalination with a sacrificial rendering mortar incorporating bamboo biochar as a novel additive. The brick samples were first freed from salt and then exposed to controlled sodium sulfate contamination. The sacrificial rendering mortar was applied to the salt-contaminated bricks. Half of the samples was left as-is, while the other half was placed in 1 cm water to mimic rising damp conditions. This procedure was repeated several times. After each application, the salt amount at different depths was measured in the bricks. The effect of biochar on the developed mortars and the desalination efficiency of the mortars were assessed, using Dino Lite digital microscopy, SEM-EDS, XRF, ion chromatography, XRD, and TGA-DTA. Preliminary results suggest that utilization of biochar incorporating sacrificial mortar is a promising ecologically friendly solution for salt mitigation.
