Current massive wall-building materials can be characterized by having either low thermal conductivities and thus low bulk densities and low compression strength or high compressions strength, high bulk densities and high thermal conductivities. In this paper, the first results of a research project are presented, in which a new aerogel-based construction material is developed that exhibits extra ordinary heat-insulating and load-carrying properties. By embedding silica aerogel granules in a high strength cement matrix “High Performance Aerogel Concrete” is developed, which combines the benefits of conventional concrete (compressive strength, unlimited moldability) with the properties of a heat insulating material. So far, various mixtures were examined in terms of their compressive strength and thermal conductivity. The first results are very promising with compressive strength between 3.0 MPa and 23.6 MPa and thermal conductivities between 0.16 W/(mK) and 0.37 W/(mK).
