摘要

波特兰水泥生产的环境负担日益增加，加速了对建筑材料可持续替代品的寻找。本文研究了以工农业废弃物为粘结剂和集料的高性能碱活化复合材料（AACs）的开发与优化。以磨粒高炉渣（GBFS）为一级前驱体，15%废砖粉（BP）、天然沸石（NZ）或稻壳灰（RHA）作为补充胶凝材料（SCMs）部分替代，100%废大理石粉（WMP）作为细骨料。目的是在不同的硅酸钠与氢氧化钠（NS/NH）比（1.5-3.0）和热固化条件（40°C和80°C）下评估这些生态高效AACs的机械、耐久性和微观结构性能，并确定高性能应用的最佳配方。

Optimization of sustainable high-performance alkali-activated composites using industrial and agricultural wastes: A comprehensive performance evaluation

The increasing environmental burden of Portland cement production has accelerated the search for sustainable alternatives in construction materials. This study investigates the development and optimization of high-performance alkali-activated composites (AACs) using industrial and agricultural waste products as binders and aggregates. Ground granulated blast furnace slag (GBFS) was used as the primary precursor, partially replaced by 15% waste brick powder (BP), natural zeolite (NZ), or rice husk ash (RHA) as supplementary cementitious materials (SCMs), while 100% waste marble powder (WMP) was employed as fine aggregate. The aim was to assess the mechanical, durability, and microstructural properties of these eco-efficient AACs under varying sodium silicate-to-sodium hydroxide (NS/NH) ratios (1.5–3.0) and thermal curing conditions (40 °C and 80 °C), and to identify the optimal formulation for high-performance applications.
