초록
The eco-friendly preservatives such as ACQ or CUAZ have been used in landscapearchitectural facilities these days. In this study, the decay efficacies of ACQ treatments wereevaluated according to domestic veneer species, concentration of ACQ, weathering test, adhesivetype, and fungus type. In case of veneer species, hinoki cypress and yellow poplar showedthe highest and lowest decay resistance, respectively. And the decay resistance appeared to begreater in plywoods bonded by resorcinol resin-bonded plywood and non-weathering treated plywoodthan polyurethane resin-bonded plywood and weathering treated plywood.
