Abstract [en]

This paper describes the initial steps towards the development of a foam concrete-aerogelcomposite for thermal insulation in lightweight sandwich façade elements. Fire safety is an important issuepertaining insulation materials. Therefore, the need for low-density inorganic, non-flammable materials israpidly increasing. Foam concrete is a lightweight material with good thermal characteristics; densities aslow as 400 kg/m3 and thermal conductivities as low as 100 mW/m·K can easily be achieved. The mainadvantage when compared to typical inorganic insulations (e.g. autoclaved aerated concrete or mineralwool) is that foam concrete has a much lower embodied energy, in particular due to the simplicity of themanufacturing process. However, in order to be competitive as an effective insulation material, thethermal conductivity needs to be drastically reduced which can be achieved by reducing the density andby incorporating silica aerogels (both measures affecting the compressive strength).
