Research on the life cycle assessment of cement

Abstract

Man-made carbon emissions from the cement sector rank second only to steel, comprising 5% of the total emissions. Additionally, the cement industry accounts for 1215% of annual energy consumption in the global industrial sector. Given the escalating climate and energy challenges, theres a growing focus on environmental impact assessments and research into low-carbon cement. Engineers are increasingly striving for carbon neutrality in cement production. Life cycle assessment (LCA) emerges as a vital tool for analyzing the environmental impact of materials throughout their lifecycle. Current research assesses LCAs applicability in the cement industry, evaluating mitigation strategies and common models. Efforts towards reducing environmental impact and optimizing cement performance are reviewed, though limitations of the LCA model in this context are noted.
