Use advice for data set When using this data set for Life Cycle Assessment, it is essential to ensure the functional unit is consistently applied as 1kg of P·O 32.5 ordinary Portland cement. The scope of the study must cover from cement raw material extraction to cement storage, including energy production and usage at the shaft kiln. Do not account for industrial waste residues used as raw materials in emissions calculations, since they are not considered a primary resource consumption. For methodological consistency, refer to the life cycle emission data provided by Di Xianghua for primary resource consumption.
Technical purpose of product or process The ordinary Portland cement (32.5 MPa) produced in this process is intended for general construction purposes. It can be used in construction projects that require a moderate level of mechanical strength. The inclusion of mixed solid wastes, such as slag, fly ash, phosphogypsum, and ceramic polishing waste, characterizes this cement process for enhanced environmental sustainability within the cement industry.
