Özet: In this study, it has been investigated that the effects of impregnation materials that are (NH3)2P, Al2(SO4)3, K2CO3, Cacl, Zncl2, on combustion properties of 3 ply laminated veneer lumbers (LVL) produced from fir (Abies bornmülleriana Mattf.) by using of phenol-formaldehyde (PF), polyvinyl acetate (PVAc). The pressure - vacuum method was used for impregnation process. Combustion test was performed according to the procedure of ASTM-E 69 standards. As a result; zinc chloride was found to be the most successful fire retardant chemical in LVL at PF adhesive. Since it diminishes combustion, the impregnation of LVL produced from fir by using PF adhesive can be advised to be impregnated by using pressure vacuum method.
