Thermosit is foamed blast furnace slag , similar to an artificial pumice stone . The grain size is 2-5 mm in diameter. The composition of this material, which is mostly used as an aggregate for concrete or in fill , can vary. Thanks to the low density of approx. 300–400 kg / m³, lightweight concrete molded parts can be poured, which allow better thermal insulation ( thermal conductivity of the aggregate: 0.16–0.21 W / (K · m)) than conventional concrete and are correspondingly lighter.

The material is no longer on the market today. Before the Second World War it was used , for example, for the roofs of industrial buildings. Today it is mostly found in building renovations.

The major disadvantage of the material is its low compressive strength and the need for prefabrication. Today, Thermosit can best be compared with foamed recycled glass gravel, which is chemically inert and mechanically more robust, has better thermal insulation properties and can even be used in in-situ concrete. The use of recycled glass gravel as a concrete aggregate in building construction instead of gravel has only been possible since the late 1990s.
