摘要
This study redefines resource efficiency in the renewable energy sector by repurposing construction waste into high-performance thixotropic soils for additive manufacturing. Our comprehensive analysis reveals that these engineered soils achieve compressive strengths up to 30 MPa—indicating a 50% increase over traditional substrates—and flexural strengths reaching 5 MPa. Rigorous life cycle assessments quantify a reduction in carbon emissions by 20% and a resource efficiency enhancement to 85%, surpassing conventional materials which average 500 kg CO2 eq/ton in carbon footprint and 60% in resource efficiency. Fine-tuned 3D printing parameters deliver unparalleled precision, achieving layer accuracy to ±0.1 mm and reducing material wastage by 30%, while accelerating construction timelines by 40%. Additionally, the materials exhibit thermal stability with only a 0.1% variation under elevated temperatures and a durability that sustains less than 0.5 MPa degradation over a 10-month period. These quantitatively robust results support the thixotropic soils' adoption, not just as a sustainable choice but as a superior alternative to conventional building materials, setting a new paradigm in the construction of environmentally resilient and economically viable renewable energy infrastructures.
