A comparative analysis study of fire resistance performance according to types of adhesives in Glued laminated timber

구조용 집성재의 접착제 종류에 따른 내화성능 비교 분석

In this study, glued laminated timber were manufactured by different types of adhesives for larch and spruce. Adhesives used to manufacture glued laminated timber include resorcinol resin, phenol resorcinol resin, melamine resin, and polyurethane. The char thickness and char rate according to the type of adhesive forglued laminated timber were analyzed. Melamine, resorcinol, and polyurethane showed excellent fire resistance performance in that order.
