Concrete

Concrete is a composite material composed of coarse aggregate bonded together with a fluid cement which hardens over time. Most concretes used are lime-based concretes such as Portland cement concrete or concretes made with other hydraulic cements, such as ciment fondu.

  • Fraunhofer WKI Develops Sustainable Sandwich Elements made from Wood Foam and Textile-reinforced Concrete

    In a joint project with the Technische Universität Braunschweig, researchers from the Fraunhofer WKI have developed an innovative building element for the construction industry: a sandwich element with a wood-foam core and a thin cover layer of textile-reinforced concrete. It can be used, for example, as a lightweight curtain-wall element or in interior fittings. The high-performance wood foam requires no artificial binding agents and can be produced from regionally available wood residues. Through the utilization of wood foam instead of conventional foam based on petrochemicals, the proportion of particularly sustainable construction materials in buildings can be increased.

    Hannover, 01/04/2019. The Bundesanstalt für Materialforschung und -prüfung (BAM) will present their research on additive manufacturing methods for complex concrete components at the Hannover Messe 2019. These methods could be used to produce tailor-made components for sewage systems quickly and economically in the future. Prototypes of various 3D printed components will be on display for those attending the trade fair.

    When integrating renewable energy into the building envelope, solar thermal plays a significant role. So far, solar thermal products were generally based on metal components that conduct heat, absorb a high fraction of solar radiation and emit little infrared radiation to prevent thermal loss. Using this state of the art technology, building integration and architectural aspects are however often neglected.
