Abstract
The article presents the NDT results of research on the influence of high temperature on the destruction of the structure of fiber-cement board as a result of the failure of a tunnel furnace. Two fiber cement boards were tested. There was a plate in a tunnel furnace during a failure, and reference plate dried in normal conditions. The research used acoustic emission method in combination with artificial neural networks.Interesting research results were obtained, which allowed to observe visible changesin the structure of the tested panels under the influence of high temperature. An important application from the point of view of building practice was formulated.
