Use advice for data set Users of this dataset should note that the data reflects the specific technological approach and environmental performance tied to Huaxin Cement Yidu Co., Ltd's technical reform indicators. The high-volume fly ash content (over 50% industrial waste slag admixture, with at least 40% consisting of slag and fly ash) should be considered when evaluating the environmental impact and applying the data to similar industrial contexts. The functional unit here is defined as the service performance of 1 kilogram of cement with a 28-day compressive strength of 42.5 MPa, crucial for comparative LCA studies. The scope of the research includes all phases from raw material pretreatment to cement storage; thus, users should include all these stages when using the data for the life cycle assessment of cement-related products.
Technical purpose of product or process This dataset represents the industrial process for the production of Portland composite cement with a compressive strength of 42.5MPa. This cement, featuring a high-volume fly ash content and incorporating mixed industrial solid wastes, such as slag and fly ash, is intended for general construction purposes where such strength level is required.
