Cement is the most widely used material in the global construction industry and one of the primary contributors to climate change. Consequently, there is a growing need to explore alternatives to cement to ensure a sustainable future for construction. Supplementary Cementitious Materials (SCMs) have gained attention for their lower environmental impact and similarities to traditional cement. This research proposes the partial replacement of cement in concrete, precisely 15%, with crushed fan shells. An impermeabilizing additive is included due to the research location in Paracas, a coastal area, to ensure concrete durability. The thesis aims to determine to what extent this proposed mixture reduces greenhouse gas emissions compared to standard concrete. Mechanical properties and the economic viability of the mixture are also evaluated. For a design tailored to local housing, an f'c of 210 kg/cm² was chosen, and Slump, compression, and flexural tests were conducted. The findings indicate that the proposed mixture is slightly more workable, has lower compressive strength, and exhibits similar flexural strength compared to standard concrete. However, after 28 days of curing, it surpasses the design compressive strength by 8%, ensuring its mechanical viability. The carbon footprint analysis, following the GHG Protocol methodology, concludes that the mixture replacing 15% of cement with crushed fan shells reduces GHG emissions by 14.94% per cubic meter compared to the standard mixture, signifying a significant carbon footprint reduction. The proposed mixture also yields substantial cost savings for producing one cubic meter of concrete, being 9.26% less expensive than the standard mixture. Based on the analysis results, it can be concluded that the concrete mixture replacing 15% of cement with crushed fan shells is mechanically viable and provides environmental and economic benefits by reducing the concrete's carbon footprint and requiring fewer materials for production.
