Use advice for data set | When employing this data set for Life Cycle Assessment, ensure that the functional unit is correctly set to 1t of this specific type of cement. The system boundary for the assessment should encompass the entire cement production process, which includes the integration of mixed solid wastes in the form of fly ash and slag. Take into account the environmental impacts associated with these wastes and how their inclusion in cement affects the LCA results. |
Technical purpose of product or process | The portland blastfurnace-slag cement produced through the new dry process is used for construction purposes, where moderate strength of 32.5MPa is adequate. It's typically utilized in concrete, mortars, and grouts where mixed solid wastes like fly ash and slag are incorporated to enhance material properties and sustainability. |
