Innovative Betone für Holz‐Beton‐Verbundkonstruktionen

Innovative concretes for timber‐concrete composite constructions. Timber‐concrete composite constructions are currently applied mainly for new buildings or when strengthening existing timber beam slabs. The load bearing capacity of timber‐concrete composite slabs is essentially affected by the material properties of the concrete slab and timber beam itself as well as the efficiency of bond between both parts. As nowadays a wide spectrum of different innovative concretes is available their applicability for timber‐concrete composite constructions has to be verified. In the following the focus is set for self‐consolidating concrete, steel fibre reinforced concrete, structural lightweight concrete, high‐strength and ultra high‐strength concrete. The advantages but also disadvantages of these concretes will be explained considering structural, economic and processing aspects and building physics.
