Because the majority of residents cannot afford cement, the majority of dwellings in Malawi are nonengineered, unreinforced masonry structures built by local artisans with no involvement from engineers. Due to the use of low-quality materials and a lack of construction detailing, these structures are highly susceptible to seismic events. It has been determined that Lime Calcined Clay Cement (LC3) is both cost-effective and a potential replacement for conventional Portland Cement (OPC). By substituting inexpensive LC3 for OPC, structures will be more resilient and durable, and CO2 emissions from the production of OPC will be decreased. Life Cycle Assessment (LCA) was utilised to compare Lime calcined clay cement (LC3) and Ordinary Portland Cement (OPC). The Environmental Footprint database was used in open LCA which contains a vast amount of data related to the environmental impacts of various products and processes. Footprint database includes data on resource consumption, emissions, and other environmental indicators associated with the entire life cycle of products. The results of the study provided strong evidence that LC3 (Low Carbon Cement) surpassed OPC (Ordinary Portland Cement) in various crucial environmental aspects. This comparison clearly showed that using LC3 instead of OPC offers significant environmental benefits, making it a more sustainable and eco-friendly choice for construction projects in Malawi. Malawi's abundant reserves of limestone and kaolinitic clay make it self-sufficient in producing the essential components of LC3 cement, which in turn, reduces the country's reliance on imported cement. This reduction in imports positively impacts Malawi's trade balance, addressing issues with the cement trade deficit. Furthermore, LC3 cement production positions Malawi to potentially access the export market, further enhancing cement exports and reducing reliance on imports.is not only more sustainable but also contributes positively to environmental preservation40enLC3OPCLime Calcined Clay CementOrdinary Portland CementMalawiLCALife Cycle AssessmentThesis
