Preparation of Portland cement with sugar filter mud as lime-based raw
The main chemical component of FM is CaO (Neha et al., 2011), which is also the main chemical compound of lime-based cement raw materials. Thereby, at least in theory, it can be used as the alternatives of lime-based materials for clinker production. There are also several advantages of utilizing FM in the cement clinker production.
