The importance of materials research is more evident than ever before and essential to solve all kind of challenges that society is facing. The chair Building Materials is devoted to the advancement and diffusion of knowledge concerning sustainable and functional building materials. Novel materials is one of the key enabling technologies in the building sector. Current research interests include:

• Sustainable and circular building (materials, energy, water).

• Granular mix design and concrete/mortar rheology (Self-Compacting Concrete, soil grouts, earth moist concrete, fiber reinforced concrete, oil well cement etc.).

• Microstructure development and pore water chemistry of hydrating cement/lime/gypsum and cementitious by-products (slag, fly ash etc.), and their dehydration (e.g. fire response).

• Treatment of contaminated soils, dredged sediments, industrial waste etc, with the help of air/steam (cleaning) and by mixing with cement/lime/gypsum (immobilization/stabilization).

• Transport properties and durability of cement/lime/gypsum based materials (Cl- and CO₂ diffusion/binding, freeze/thaw etc.).

• Functional materials: self-cleaning, air-purifying, translucent, thermally buffering, etc.
