Abstract

Wood preservatives have been widely used to extend the service life of
wood. The most objectionable environment for wood is outdoor conditions. In
this study, test specimens prepared from chestnut wood (Castanea sativa Mill)
were impregnated with natural and chemical impregnation agent. It was aimed to
determine the effect of outdoor conditions on physical and mechanical
properties of wood material by keeping them under these conditions for one
year.

As natural impregnation material pine tannin and acorn tannins, as
chemical impregnation material imersol aqua and timbercare aqua were used. The
retention amount, air-dried density, bending strength, modulus of elasticity,
compression strength parallel to fibers, adhesion strength parallel to fibers,
screw withdrawal strength were determined.

As a result, it can be said that the physical and mechanical test values
can compare wood impregnated with natural impregnation materials to wood
impregnated with chemical impregnation materials after one year exposed to
outdoor conditions.
