Method of determination the initial elasticity modulus and timber deformation modulus under the influence of acid environment

Анотація

The technique of experimental researches of timber by axial compression along fibers by short-term loading for operation in various acid environments (hydrochloric, acetic and lactic acids) during displacements increase is developed. The results of researches of the initial elasticity modulus and the deformations modulus taking into account the factor of environment aggressiveness are given. It is found that the effect of acids on wood with different impregnation periods significantly reduces the initial elasticity modulus and deformation modulus and depends on the impregnation period.
