The Building Materials research topic consists of 19 people, including five professors and two postdocs. The subject focuses on the development of sustainable materials and production techniques for the construction industry, as well as on research and education related to ice and Arctic conditions. Subject description Building Materials includes sustainable building materials and their application, recycling and reuse, and applied building physics, with a particular focus on Arctic conditions. Project description The green transition of Sweden is in full swing. The task of achieving sustainable, circular and resource-efficient community building is extremely demanding. Most of that responsibility falls on the construction industry. This sector is the driving force for new constructions, but also for the maintenance, modernization and demolition of existing structures. The construction industry relies heavily on concrete, which is characterized by a very high CO2 footprint, mainly related to the use of Portland cement. The project aims to address the sustainability of concrete and building materials as well as resource efficiency by developing a new method to produce zero-emission concrete using only recycled materials.
