Traditional Portland cement (TPC) production.The content of slag in slag-based cement (SBC) was about 10%. The slag can replace the clay in cement production, and also effect the energy consumption during grinding process due to its poor grindability. Data users should consider this LCA data specifically for cement production employing slag inclusion, with the slag content at about 10%. Bear in mind the slag’s influence on energy consumption during the grinding process. The system boundaries provided include only the stages from mining to transportation; users evaluating wider environmental impacts should include subsequent cement use and end-of-life phases. Data applicability should be limited to contexts with technology levels and production scales resembling typical Chinese cement plants described herein.
