Cement bonded wood-wool as external walls have been used around the world since the 1980s. They can have different appearances, wood-wool slabs connected to each other into larger wall elements that are raised between concrete columns and beams. Another type is hollow wood-wool blocks that are stacked on each other and filled with concrete to make an external wall. In 2004 a new building system was launched in Sweden, large prefabricated wall elements of wood-wool. They are connected to each other with concrete columns and beams integrated in the elements to make an external wall. This report is looking into if the concrete beams and columns for the building system are needed. In the report three different tests were made to get the mechanical properties of the prefabricated wood-wool elements. Results showed that there was a large different in the density between the wall elements and it also showed that the modulus of rupture varied between 0.248-0.449 MPa on three identical wall elements. The characteristic modulus of rupture was three times higher than documented in previous reports of a similar wall. The conclusion of this report is that the concrete beams and columns should still be in the wall system.
