INCREASING THE FIRE RESISTANCE OF TIMBER STRUCTURES AND BUILDINGS USING MODEL TESTS WITH FIRE RETARDANTS

Today, an urgent problem in modern construction is the development of highly functional fire-resistant solutions to protect the timber from destruction and the effect of fire on it, which are characterized by the high efficiency of the penetration of these solutions into the middle of the timber, the durability of their protection and operational properties to ensure the longevity of the operation of timber structures. One of these fire-resistant solutions is a solution invented on the basis of the method of impregnation of timber based on area. In this work, we provide an analysis of modern methods of calculated tests regarding the quality of impregnation of timber structures and timber products made of timber with protective fire-resistant solutions (fire retardants), as well as the schemes of these model tests.
