Název v původním jazyce

Mechanical characteristics of chemically degraded surface layers of wood

Popis výsledku v původním jazyce

The aim of this research was to find out whether the effect of chemical corrosion changes mechanical characteristics of surface layers of wooden construction elements. Degradation of the surface layers of wood was caused by chemical reactions of the basic substances of wood mass with compounds contained in antifire coatings. Fire retardants containing corrosive substances were often and repeatedly used in the Czech Republic on many wooden building constructions. This process of chemical corrosion is inpractise called as "surface defibering of wood". This contribution presents standard and special experimental methods used for measuring the selected mechanical characteristics (compression strength, tension strength, bending strength, hardness and impact resistance) in the damaged surface layer of wooden construction elements. The material for experimental measuring was a construction element removed from a historical roof (ca 150 years old). Mechanical characteristics of the surface la
