Description

Moisture is one of the most important causes for building pathology. The material degradation can be affected by the presence of water, both in vapour and liquid phase. Wood has a strong hygroscopic behaviour, with a strong variation of moisture content and dimension stability caused by modifications of the relative humidity of the surrounding air. The properties that define the behaviour of wood against temperature and moisture actions were studied in this work. Hygroscopicity and shrinkage were given special attention.
