Study on Creep Performance of Fast-growing Poplar modified with ACQ-D

People have paid more attention. to continuous developing environmental quality since the new century. Now, designers attach importance to wood materials that could be used in construction. However, wood is liable to be attacked by fungi and insects. It is necessary to enable wood materials with strong anti-decay ability when the material is to be used in exterior applications. The major wood materials which could gain easily are based on wood from fast-grown trees. Therefore, fast-grown poplar was chosen for this experiment. Fast-grown poplar samples were modified with ACQ-D. Furthermore the static mechanical and creep performance of this modified wood should be emphasized and measured when used as structural materials. The results showed that the mechanical strength of modified samples is almost equal to that of the unmodified. However, the anti-creep performance of modified samples was lower than that of the unmodified under the same bearing scales. Wood samples were much more affected by relative humidity after treatment with ACQ-D.
