Prognosis method of wooden structure durability

Abstract

The relevance of the studied topic is due to the fact that, despite the longtime wood use as a building material, the issue of durability predicting keeps underexplored. Wood offers a wide range of positive properties, but still has a number of disadvantages, one of which is a tendency to biodeterioration. The main way to control wood biodeterioration is its antiseptic treatment. However, during the operation or storage of treated wooden structures, there is a process of washing out antiseptic agents from them (depreservation) and, as a result, a decrease of biostability. The paper proposes the methodology for accelerated prediction of the wood treated durability with an antiseptic, taking into account the real conditions of its operation. The optimal conditions and the temperature effect on the rate of diffusion antiseptic transfer to external environment are established, depending on the actual operating conditions of wooden structures.
