Analysis of the fire-protection impregnation influence on wood strength

Abstract

The paper presents the description, results and result analysis for the effect of fire-protection impregnation with a salt-containing agent, made by a vacuum-and-pressure method, on wood strength. A significant effect of this impregnation type was proven for the strength types as follows: static bending, tension, lengthwise compression (ie along fibres), crosswise compression (ie across fibres), as well as for dynamic bending and impact strength in normal and elevated temperatures.
