Preparation and characterization of Portland cement clinker from …
The analysis results for the synthesized oyster-shell cement (OSC) and scallop-shell cement (SSC) were compared with those of limestone-based cement and commercial ordinary Portland cement (OPC). Anhydrous cement-clinker phases such as C 3 S, C 2 S, C 3 A, and C 4 AF were successfully formed in all the synthesized clinkers, similar to the OPC.
