Abstract
The invention relates to a method for manufacturing a belite cement clinker The method comprises steps of providing raw materials comprising 10 to 90 wt.% green liquor dregs (GLD), and 0 to 50 wt.% bio-based fly ash, based on total dry weight of the raw materials, and heating a mixture comprising the raw materials in a thermal treatment unit by using a process temperature and a residence time. The invention further relates to a belite cement clinker. The invention further relates to a belite cement composition. The invention further relates to method for manufacturing a belite cement composition.
