Thermal expansion of wood at different equilibrium moisture contents | Journal of Wood Science | Full Text

The measurement of the relation between the thermal expansion of wood and its moisture content is a very difficult task, as the wood equilibrium moisture content (EMC) is directly related to both the temperature and relative humidity (RH) of the surrounding air. Therefore, EMC changes with air T, even when maintaining RH constant.

Thermal properties of wood | Wood Products

The thermal expansion of wood in the direction of the grain is very little. In the radial and tangential directions, temperature movements are much greater. The relationship between the thermal expansion coefficients and moisture contraction coefficients of wood in different directions relative to the grain is in the same class in terms of size.

Thermally modified wood - Wikipedia

Thermal wood treatment has already been penetrating the market for a number of years. There is also some industrial input in the research and development. The Natural Resources Research Institute at the University of Minnesota Duluth has a pilot-scale kiln to research the effectiveness of thermal modification on underutilized Minnesota tree species to expand the wood markets.

Describes and illustrates the apparatus used in experiments to determine the coefficient of thermal expansion of moistureless specimens of Beech and Scots Pine. The experiments showed that thermal movements of wood are of small significance, being ca. 1/18 and 1/15 that of the corresponding moisture movements in Beech and Pine respectively.

We have investigated tension wood cellulose obtained from Populus maximowiczii using X-ray diffraction at temperatures from room temperature to 250 °C. Three equatorial and one meridional d-spacings showed a gradual linear increase with increasing temperature. For temperatures above 180 °C, however, the equatorial d-spacing increased dramatically. Thus, the linear and volume thermal ...

The normal range is 1–4 × 10+6 /°C, although individual aggregates may fall outside, and extreme values are 0.3 × 10 −6 and 5 × 10 −6 /°C. The thermal expansion of cement pastes is about 5–6 × 10 −6 /°C and it is rare for aggregates to have expansions greater than this.
