Study on Eco-Economic Sustainable Development of Innovative Construction Materials

This study compares the performance data of innovative construction materials, represented by reed fiber-reinforced concrete, with those of conventional ordinary concrete. Using a Life Cycle Assessment (LCA) model and a sustainable development model, this paper investigates the energy consumption and environmental impact of different building materials throughout their life cycles. Key parameters analyzed include density, flexural-tensile strength, compressive strength, energy consumption, and carbon footprint of reed fiber-reinforced concrete versus conventional concrete. The results indicate that both non-metallic fibers (e.g., reed fibers) and metallic fibers can effectively enhance the mechanical properties of structural concrete. Model calculations reveal the following comparative data‐‐Reed fiber-reinforced concrete: Cost 380 CNY/m 3 , Energy consumption 25 kWh/m 3 , Carbon footprint 80 kg CO 2 /m 3 . Conventional concrete: Cost 450 CNY/m 3 , Energy consumption 35 kWh/m 3 , Carbon footprint 100 kg CO 2 /m 3 . The findings demonstrate that reed fiber-reinforced concrete exhibits superior sustainability in terms of cost efficiency, energy savings, and reduced carbon emissions, providing critical insights for future material selection in construction.
