This chapter investigates the robustness and durability of concrete reinforced with fly ash and silica fume, emphasizing the potential environmental and economic benefits of using these industrial by-products. By integrating life cycle assessment (LCA) and techno-economic assessment (TEA) frameworks, this study provides a holistic evaluation of the material’s sustainability. Experimental findings indicate that replacing 20% of cement with fly ash and 6% with silica fume yields optimal performance, achieving compressive strength values up to 44.04 N/mm2 after 90 days and split tensile strength of 4.41 N/mm2. This mix also showed enhanced flexural strength and resilience against chemical exposures, with a 15% higher resistance to acid attack compared to conventional concrete. The LCA results reveal a 25% reduction in carbon emissions and 18% lower energy consumption, while TEA analysis demonstrates a 12% reduction in production costs. This study ultimately highlights the role of sustainable materials in advancing eco-efficient construction practices and supports the viability of incorporating fly ash and silica fume for improved environmental and economic outcomes.

摘要

This chapter investigates the robustness and durability of concrete reinforced with fly ash and silica fume, emphasizing the potential environmental and economic benefits of using these industrial by-products. By integrating life cycle assessment (LCA) and techno-economic assessment (TEA) frameworks, this study provides a holistic evaluation of the material’s sustainability. Experimental findings indicate that replacing 20% of cement with fly ash and 6% with silica fume yields optimal performance, achieving compressive strength values up to 44.04 N/mm2 after 90 days and split tensile strength of 4.41 N/mm2. This mix also showed enhanced flexural strength and resilience against chemical exposures, with a 15% higher resistance to acid attack compared to conventional concrete. The LCA results reveal a 25% reduction in carbon emissions and 18% lower energy consumption, while TEA analysis demonstrates a 12% reduction in production costs. This study ultimately highlights the role of sustainable materials in advancing eco-efficient construction practices and supports the viability of incorporating fly ash and silica fume for improved environmental and economic outcomes.
