Performance of Constructions with Clay Plaster and Timber at Elevated Temperatures

The combustibility of timber is one of the main reasons that too many building regulations and standards restrict its use. Lack of understanding of the fire technical properties of clay plaster is what most likely prevents this traditional material in combination with timber from being widely used. The purpose of the following research is to designate the fire technical properties for clay plaster for the fire design of timber structures. For this study the fire testing of clay plaster was carried out in small and model scale to determine the main characteristics. In this paper the recommendations for the improvement of the design method for timber structures with clay plaster according to the safety philosophy of Eurocode 5 Part 1-2 are published.
