THE EFFECT OF MOISTURE ON SELECTED MECHANICAL PROPERTIES OF CROSS-LAMINATED TIMBER MANUFACTURED FROM BLACK PINE WOOD

Abstract

In recent years, interest in wooden and cross-laminated Timber (CLT) materials has begun to increase. CLT is widely used in the construction of wooden structures in many countries. This material has also begun to be used in the construction of multi-storey buildings. Structural wooden materials used in the construction of multi-storey buildings must have high mechanical performance. However, wood is a material whose mechanical performance changes when it gets moisture. The aim of this study is to determine the effect of moisture on selected mechanical properties of CLT material produced from Black pine wood. For this purpose, 3-layer cross-laminated wood is produced using polyurethane glue. The produced building material was subjected to selected mechanical tests in both air-dry and wet states. Three-point bending strength, modulus of elasticity, deformation at bending, bonding strength, and nail withdrawal resistance of the CLT material were determined. According to the data obtained; It was determined that the bending strength, modulus of elasticity, nail withdrawal resistance and bonding strength of the air-dry test samples were 127%, 118%, 35% and 87% higher, respectively, than those of the wet test samples. It was determined that the bending deformation amount of the wet test samples was 52% higher than that of the dry test samples.
