The burgeoning demand for durable and eco-friendly road infrastructure necessitates the exploration of innovative materials and methodologies. This study investigates the potential of Graphene Oxide (GO), a nano-material known for its exceptional dispersibility and mechanical reinforcement capabilities, to enhance the sustainability and durability of concrete pavements. Leveraging the synergy between advanced artificial intelligence techniques-Artificial Neural Networks (ANN), Genetic Algorithms (GA), and Particle Swarm Optimization (PSO)-it is aimed to delve into the intricate effects of Nano-GO on concrete's mechanical properties. The empirical analysis, underpinned by a comparative evaluation of ANN-GA and ANN-PSO models, reveals that the ANN-GA model excels with a minimal forecast error of 2.73%, underscoring its efficacy in capturing the nuanced interactions between GO and cementitious materials. An optimal concentration is identified through meticulous experimentation across varied Nano-GO dosages that amplify concrete's compressive, flexural, and tensile strengths without compromising workability. This optimal dosage enhances the initial strength significantly, and positions GO as a cornerstone for next-generation premium-grade pavement concretes. The findings advocate for the further exploration and eventual integration of GO in road construction projects, aiming to bolster ecological sustainability and propel the adoption of a circular economy in infrastructure development.
蓬勃发展的耐用且环保的道路基础设施需求需要探索创新材料和方法。本研究探讨了氧化石墨烯(GO)的潜力,GO 是一种纳米材料,以其出色的分散性和机械增强能力而闻名,可提高混凝土路面的可持续性和耐久性。利用先进的人工智能技术——人工神经网络(ANN)、遗传算法(GA)和粒子群优化(PSO)之间的协同作用,深入研究纳米 GO 对混凝土机械性能的复杂影响。实证分析以 ANN-GA 和 ANN-PSO 模型的比较评估为基础,结果表明 ANN-GA 模型表现出色,预测误差最小为 2.73%,突出了其在捕捉 GO 和胶凝材料之间细微相互作用方面的有效性。通过在不同纳米 GO 剂量下进行细致的实验,确定了最佳浓度,在不影响工作性的情况下提高了混凝土的抗压、抗弯和抗拉强度。最佳剂量显著提高了初始强度,使 GO 成为下一代优质路面混凝土的基石。研究结果主张进一步探索并最终将 GO 纳入道路建设项目,旨在增强生态可持续性并推动基础设施发展中采用循环经济。
