Use advice for data set When using this LCA data, ensure that it aligns with the scope of your study. It is suitable for assessments of cement production emissions and energy consumption without consideration for mining, transportation, or packaging processes. Be cautious when applying this data to projects outside the defined scope, and recalibrate it based on specific regional conditions or technological variations if necessary. When calculating CO2 emissions, adhere to the methodological guidelines provided for evaluating functional units and scaling to other production quantities.
Technical purpose of product or process The described industrial process details the production of Portland fly-ash cement with a strength grade of 52.5MPa using a dry process precalciner kiln. This grade of cement is utilized in various construction projects requiring high strength cement, including infrastructure such as bridges, buildings, roads as well as in residential construction. The process is highly controlled by a computer automation system and involves advanced equipment for the grinding and calcination of raw meal and clinker.
