Winter Shelters For Marble Sculptures Of The Schlossbrücke Berlin: Climatic Constraints
- The long-term exposure of marble objects leads to a successive deterioration of the rock fabric and may cause severe damage on cultural heritage objects. The magnitude of disintegration depends on the rock fabric as well as on the climatic conditions. Some types of marble show no considerable damage even if they have been exposed in northern Europe for several decades or centuries. In contrast, other marble varieties are showing severe damage after a few years of weathering. The present study shows that marble decay, along with the initial thermal degradation, is mainly influenced by the hygric and thermo-hygric load, respectively. The influence of the rock fabric on the resistivity against weathering is also documented. The factors causing marble decay were compared to extensive climate data, which were collected during a scientific project that was started with the aim to develop a covering system for marble sculptures in Berlin.

The factors causing marble decay were compared to extensive climate data, which were collected during a scientific project that was started with the aim to develop a covering system for marble sculptures in Berlin. Based on the hygrothermal material properties of the marble and on the climatic conditions, the heat and moisture Transport inside the material and hence the hygrothermal load changes were calculated with a high spatial resolution. The calculations showed that the temperature and moisture fluctuations inside the material are mainly controlled by the dimensions and orientation of the sculptural elements. The current state of preservation was investigated by two-dimensional ultrasonic tomography. The results show a good correlation to the calculated distribution of the hygrothermal load. Based on this finding, requirements on a protective winter shelter system for the sculptures were defined. The project results show that in addition to protective covers, regular inspection and maintenance combined with regular cleaning ensures an effective and sustainable protection of marble objects in northern Europe.…
