Description
This dataset represents the production of fly ash Portland cement at an average strength, obtained by weighting the market shares of 32.5, 32.5R, 42.5, 42.5R, 52.5 and 52.5R fly ash Portland cement. For technical details, refer to the production datasets of fly ash 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
Fly ash Portland cement is a hydraulic cementitious material made of Portland cement clinker and fly ash as the main components, mixed with an appropriate amount of gypsum. It is suitable for large-volume concrete projects on the ground, underground and in water, steam-cured concrete components, and general projects with corrosion resistance requirements.
