Description
This dataset represents the production of composite Portland cement at an average strength, obtained by weighting the market shares of 42.5, 42.5R, 52.5 and 52.5R composite Portland cement. For technical details, refer to the production datasets of composite 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
Composite Portland cement is a hydraulic cementitious material made by grinding Portland cement clinker and three or more mixed materials as the main components with an appropriate amount of gypsum. It is suitable for concrete projects in high-humidity environments or long-term immersion in water, thick and large-volume concrete projects, and concrete projects exposed to corrosive media.
