Wood is a versatile, but also complex construction material. Its properties vary due to many factors, such as species, the presence of knots or fibre orientation in the tree and …
The elusive wood-water relations have been studied for over a century and are among the most researched topics in wood material science. Wood-water relations originate from the polar hydroxyl groups …
The construction sector stands for a large amount of the global carbon dioxide emissions and reducing these is thus important to prevent global warming. One benefit with building in wood …
Stress Laminated Timber (SLT) is a construction system created by compressing multiple layers of timber together with steel tendons. The stress part in the name implies that stress or pressure …
Wood is a hydrophilic material and the moisture content of it depends from the relative humidity of environment. It’s known that the moisture content of wood have an influence to …
The moisture content (mc) of wood is of great importance to several processes in mechanical pulp mills. Debarking, chipping, refining and indirect bleaching are factors that are affected by the …
The gravimetric method that is used today to determine the moisture content in wood is very tedious. The results are received after 24 hours, and it can be quite hard …
In this study the moisture content of Norway spruce stump wood after harvesting was examined. The material was collected immediately after harvesting at the clear cutting area and after different …
Effect of thermal treatment on the bending strength of black alder wood was examined. The wood samples were treated at temperature of 60, 80 100 and 120°C and duration for …
The use of plant biomass for energy purposes, including forest residues and underbrush, has many advantages in comparison to fossil fuel. It is considered that underbrush consisting of bushes and …
The measurement of the amount of energy wood can be based on volume (m3), weight (kg) or energy content (MWh). Physically the measuring can be made in the forest, at …
The relationship between relative humidity and wood moisture content is shown in a sorption isotherm. However, the moisture content of a material depend not only on the relative humidity but …
Bound water states in small wood samples were investigated by means of time-domain nuclear magnetic resonance. A bench-top low-field NMR instrument (Bruker minispec mq20) with a proton resonance frequency of …
The purpose of this study was to explore the possibility to surface densify acetylated solid wood. The aim of surface densification is to improve mechanical properties, such as hardness, at …
This project is a part of development of overall work to be finished as Master’s thesis of Technology of Wood and Plastic study program. As Cross Laminated Timber (CLT) is …
