This study thoroughly reviews the recent design methods for ultra-high-performance concrete (UHPC) with agricultural waste. The goal is to identify UHPC composites that meets environmental sustainability requirements while fulfilling workability, durability, and mechanical properties. The capacity of typical review studies is limited in bridging the various literature aspects systematically. The article includes comparative analyses identifying these methods’ intrinsic connections and current trends. The analysis indicates that 71% of documents on incorporating agricultural waste into UHPC are in the “Engineering” and “Materials Science” disciplines, with 69% being journal articles, and 27% conference documents. Significant research keywords involve “Ultra-High-Performance Concrete,” “Cements,” “Sustainable Development,” and “Agricultural Wastes,” highlighting the extensive exploration of agricultural waste in UHPC. It has been discovered that agricultural waste can replace silica fume in UHPC, improving strength and durability by reducing pore volume and enhancing microstructure. Substituting 5–30% of cement with rice husk ash significantly boosts compressive strength, enhancing cement hydration, pore structure, and pozzolanic reaction, offering substantial environmental benefits and supporting the construction industry’s contribution to low-carbon sustainable development. This article provides guidance and recommendations for developing sustainable UHPC to meet diverse design specifications, promoting environmentally friendly construction practices.

探索农业废弃物作为可持续建筑超高性能混凝土添加剂的潜力：全面综述

本研究全面回顾了农业废弃物超高性能混凝土（UHPC）的最新设计方法。目标是确定 UHPC 复合材料满足环境可持续性要求，同时满足可加工性、耐用性和机械性能。典型综述研究的能力有限，无法系统地衔接各个文献方面。本文包括比较分析，以确定这些方法的内在联系和当前趋势。分析表明，关于将农业废弃物纳入UHPC的文献中有71%属于“工程”和“材料科学”学科，其中69%是期刊文章，27%是会议文件。重要的研究关键词涉及“超高性能混凝土”、“水泥”、“可持续发展”和“农业废弃物”，凸显了UHPC对农业废弃物的广泛探索。人们发现，农业废弃物可以替代 UHPC 中的硅粉，通过减少孔体积和增强微观结构来提高强度和耐久性。用稻壳灰替代5-30%的水泥可显着提高抗压强度，增强水泥水化、孔隙结构和火山灰反应，带来显着的环境效益，支持建筑业为低碳可持续发展做出贡献。本文为开发可持续 UHPC 以满足不同的设计规范、促进环保的施工实践提供了指导和建议。
