摘要：
A study was carried out to compare the performance of glulam of heat-treated wood with glulam of untreated wood with respect to the gluability properties. The heat-treated wood was treated to comply with performance requirements for above-ground end-uses. Small glulam beams were made of untreated and heat-treated pine and spruce. Two different adhesives, PRF (Phenol-Resorcinol-Formaldehyde) and PVAc (Poly-Vinyl-Acetate) were used. A delamination test was carried out according to EN 391, method B. The study confirmed that gluing of heat-treated wood needs special consideration. The PRF adhesive performed very well whereas the PVAc adhesive showed an unacceptable percentage of delamination and thus seems to be unsuitable for gluing heat-treated wood, at least without modification of the gluing process.
