Thermophysical characterization of a laminated solid-wood pine wall

Hygrothermal properties of cross laminated timber and moisture response of wood at high relative humidity

“…The research included testing four different CLT specimens for various hygrothermal properties including EMC, water vapour permeability, liquid water absorption, thermal conductivity and air permeability. The test results were validated against the experimental work conducted by other studies such as Time (1998), Wu (2007) and Raji et al (2009). On the other hand, a parametric study, with different EMC curves (i.e.…”

“…Various researchers have determined the sorption properties of wood (Tveit 1966, Ahlgren 1972, Absentz 1993, Time 1998and Raji et al 2009. These properties will be used to relate the sorption of CLT to that of wood.…”

“…Also, Table 3.3 shows that the conductivity of the material is dependent on the density of the material. Raji et al (2009) tested a laminated pine specimen for thermal conductivity. Results ranged between 0.08 and 0.14 W/m-K for a MC less than 0.1 kg/kg, and between 0.22 and 0.3 W/m-K at higher MC.…”

“…The performance of the material can be described in air permeance (kg/m2 Pa s) Wu (2007) reported air permeance of spruce to be (7.2 ±1) x 10'9 kg/m■ Pa-s using pressure differences ranging from 50 to 350 Pa. Moreover, Raji et al (2009) tested specimens with and without laminate, and found that specimens with laminate had low air permeability. It was concluded that the difference in air permeability will have minimal influence due to the very low permeability of wood at large thicknesses.…”

“…Se han realizado diferentes estudios similares para especies de pino y encino europeo (Fernandez y Howell, 1997;Raji et al, 2009;Turner et al, 1998), sin embargo, para especies de pinos mexicanos existen pocos estudios con el enfoque de este trabajo, por lo que al modelar el proceso de secado se obtendrá información que podría utilizarse en la elaboración de modelos de secado más complejos que se apliquen en la optimización del diseño y control automático de secadores para especies endémicas, además de contribuir con el aprovechamiento forestal mexicano.…”
