We have published our second bulletin of the LIFE EcoTimberCell project in Spanish, English, Galician and Catalan language. It is available for download in the resources section of our website.
The second LIFE EcoTimberCell newsletter is dedicated to the first actions of the project:
- Characterisation of local wood
- Characterization of the Betanzos HB board that is part of the EcoTimberCell
- Reaction to fire and application parameters of structural adhesives
It also incorporates the news that happened during the project.
We summarize here what you can find in each chapter of the bulletin:
Characterization of local wood:
The variability in the properties of wood in different forest species makes the classification under parameters of resistance, rigidity and density complex, in LIFE EcoTimberCell we address this issue. In the bulletin we highlight that the University of Santiago de Compostela (USC) has developed a process of characterization of wood that firstly takes into account the singularities of the material through a visual classification (UNE 56544 and UN 56546 standards) and mechanical properties independently, with the realization of experimental tests applying non-destructive and destructive methodologies. In which they used the standardized resistance classes at European level defined in the EN338 standard.
Characterization of the Betanzos HB board
We describe how we characterize the hardboards of Betanzos HB, project partner, through different tests to obtain their stiffness properties and the characteristic value of their resistant properties. This work was carried out by the USC together with Betanzos HB itself. Obtaining as a result a series of possibilities of improvement of the board to implement in future actions of the project. This characterization of the boards was carried out according to the UNE EN 789 Standard.
Reaction to fire and application parameters of structural adhesives.
The reaction to fire performance is a key aspect in any element
building. These performances are defined according to two normative tests: flammability and exposure to burning objects. In the bulletin, the Centre for Forestry and Wood Technology of Asturias (CETEMAS), in collaboration with Betanzos HB, details the work carried out and the conclusions obtained in the project. Likewise, the work on the characterization of the ecological lignin adhesive in the LIFE EcoTimberCell project is also included.
The characterisation tests were carried out by the laboratory of the Platform for Structural Wood Engineering (PEMADE) of the USC and the tests on reaction to fire and application parameters of structural adhesives were carried out by CETEMAS
