1. Introduction and applications

Saving energy and avoiding carbon emissions are the challenges of our time. Cement-based construction materials account for 7% of global carbon emissions and thus contribute significantly to climate change. However, since the overall availability of alternative materials is very limited and even these do not necessarily contribute to climate-neutral construction, other routes towards more sustainable construction must also be taken, such as the increased use of recycled materials and the production of single-material components and lightweight materials that...
