A refurbishment material with great potential
Timber beam floors often need to be strengthened as a result of changes in building use or because of increasingly demanding requirements. A tried and tested approach to achieving this is to create a shear-resistant bond between the existing timber beams and a subsequently added concrete layer. This method results in a timber-concrete composite element with significantly improved load-bearing capacity, stiffness and thermal characteristics. The concrete slab forms part of the composite section and is subjected to the corresponding actions, which is why it must usually be reinforced. Compared...
