Description
This dataset represents the production of ordinary 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 ordinary Portland cement. For technical details, refer to the production datasets of ordinary 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
Ordinary Portland cement is a hydraulic cementitious material produced by grinding Portland cement clinker, mixed materials (not exceeding 20% of total cement mass) as main constituents, together with an appropriate amount of gypsum. It is suitable for general civil engineering works and projects exposed to freezing action.
