About Paper:

The construction material industry is recognized as one of the largest and most energy-intensive sectors globally, contributing significantly to carbon emissions. Specifically, the cement and concrete industry alone accounts for approximately 1,500 megatons/year of CO2 emissions, translating to around 0.8 to 1.0 ton of CO2 per ton of cement produced. This makes cement production responsible for approximately 8% of global carbon emissions, making it a significant contributor to climate change. To address these concerns, this project aims to investigate the environmental impact of construction materials through the implementation of a life cycle assessment (LCA) model. LCA is a methodology used to assess the environmental impacts associated with all stages of a commercial product, process, or service's life cycle. By utilizing LCA, we can analyze and compare the environmental friendliness of different construction materials, such as Ordinary Portland Cement (OPC), Portland Limestone Cement (PLC), and other types of cement, during the manufacturing process. Additionally, the project will employ the Life Cycle Impact Assessment (LCIA) process to evaluate the potential consequences of the inventory data obtained from the LCA. LCIA allows decision-makers and professionals to gain a deeper understanding of the environmental harm resulting from resource consumption and emissions, including impacts like global warming, stratospheric ozone depletion, and terrestrial acidification. These potential impacts will be evaluated to determine which construction materials are more sustainable and environmentally favorable. It is important to continue future studies that build upon this model in order to provide compelling results and further insights into sustainable construction practices.
