Abstract

This study explored the usability of basil plant ash (BPA) as an eco-friendly supplementary cementitious material for ultra-high-performance concrete (UHPC). This study sought to determine the impact of BPA on the mechanical properties, durability, radiation-shielding ability, environmental sustainability, and economic efficiency of UHPC. The control mix was free of BPA, whereas the investigated mixes were set at 10–40% replacement of cement weight. The concrete composite was examined using scanning electron microscopy(SEM) and X-ray diffraction(XRD) analysis. The radiation protection properties against γ-rays and neutrons were evaluated using Monte Carlo(MC) simulations and the Phy-X online software. The environmental impact was assessed by calculation of carbon dioxide emissions resulting from the concrete production process. An environmental impact assessment revealed that incorporating 30% BPA reduced carbon dioxide emissions by 27% during concrete production. These findings highlight the potential of BPA as an eco-friendly additive to enhance the mechanical, durability, and radiation-shielding properties of UHPC while reducing its environmental impact and production costs.

罗勒植物灰UHPC的优化：对强度、耐久性和γ射线衰减的影响

本研究探讨了罗勒植物灰（BPA）作为一种环保的高性能混凝土（UHPC）补充胶凝材料的可用性。本研究旨在确定BPA对UHPC的机械性能、耐久性、辐射屏蔽能力、环境可持续性和经济效益的影响。对照混合料不含双酚a，而研究混合料的替代量为水泥重量的10-40%。采用扫描电子显微镜（SEM）和x射线衍射仪（XRD）对混凝土复合材料进行了检测。利用蒙特卡罗（MC）模拟和Phy-X在线软件对其对γ射线和中子的辐射防护性能进行了评估。通过计算混凝土生产过程中产生的二氧化碳排放量来评估环境影响。一项环境影响评估显示，在混凝土生产过程中，掺入30%双酚a可减少27%的二氧化碳排放量。这些发现强调了双酚a作为一种环保添加剂的潜力，可以增强UHPC的机械、耐用性和辐射屏蔽性能，同时降低其对环境的影响和生产成本。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
