Lightwood-concrete: revitalization of Viennese old buildings

01.07.2010 - 31.05.2011
Research funding project
An aim of the research project is to develop innovative shear stiff wall and floor systems in respect of reduction of the dead load, minimization of the dimensions of the floor components and increasing the thermal insulation as well as fire safety. These will be optimized by the variation of construction layers and their geometry. The research project includes design concepts, feasibility studies and performance assessments as well as the optimization of manufacturing methods of the components in order to improve the overall performance (see Appendix 1). In order to develop a multi-layer shear wall and shear stiff floor system composed of lightweight wood-concrete -this new technology involves the addition of wood material such as chips; saw dust, residual or recycled wood as permanent aggregate in concrete-, the lightweight wood-concrete composites, the adhesives as well as the connection between these components and the timber sections will be investigated. To achieve relevant results compatible to industrial applications following issues will be evaluated:  Strength tests and evaluation of the physical properties of the lightweight wood-concrete,  Design of wall and floor components made of lightweight concrete connected to timber sections,  Development of various sets of prototypes for testing,  Shear and bending tests of the prototypes,  Analysis of the experimental results to develop design concepts,  using recycled wood particles and new additives,  Optimization of the manufacturing methods,  Studies regarding the ecological impact,  Evaluation of the thermal and sound insulation behavior. The lightweight wood-concrete construction systems allowed:  Use of wood both as permanent formwork and as concrete reinforcement;  Reduction of the dead load and increasing the thermal insulation;  Minimization of the dimensions of the timber and concrete components;  Creation of environmental-friendly construction made of renewable resources;  Reduction of energy consumption by using low-energy materials and energy-efficient systems
