Description
This dataset represents the production of Portland cement at an average strength, obtained by weighting the market shares of 42.5, 42.5R, 52.5, 52.5R, 62.5 and 62.5R Portland cement. For technical details, refer to the production datasets of Portland cement of each strength grade. The data are mainly sourced from official industry statistical reports.
Activity Description
The production system boundary of this product is the grinding stage of cement production, including cement grinding, flue gas denitration, particulate matter removal, and flue gas desulfurization. The process used can basically realize the full cycle of water, and part of the loss is treated as non-recyclable waste.
Process Description
Portland cement is a hydraulic binder produced by grinding Portland cement clinker with an appropriate amount of gypsum; 0-5% of additional constituents may be added. It is suitable for high-strength and prestressed concrete used in important structures.
