Abstract
The durability state of Populus nigra wood after 3 years of contact with ground. Poplar wood is considered soft, lightweight, characterised by low mechanical properties and rather low durability as regards fungi and contact with ground. Those properties may limit the scope of its applications in such conditions, e.g. as terrace boards. Thermo modification is a process which may remedy some of those disadvantageous properties, particularly low durability. The aim of this research was to identify the resistance of thermally modified poplar wood after 3 years of contact with the ground according to EN 252 method, in comparison to natural twin wood of this species. The paper presents detailed differences between the features of natural and thermo modified poplar wood, which were studied during field exposition of the wood. It was observed that thermo modified poplar wood decayed slower in contact with the ground compared to the natural wood of the species, and the difference after 3 years was quite significant (rating 3.6 and respectively 2.2).
