📄 Abstract（原文）
The global construction industry's reliance on ordinary Portland cement (OPC) contributes approximately 8% of worldwide CO₂ emissions, representing one of the most urgent decarbonization challenges of the 21st century. This comprehensive literature review synthesizes over six decades of research on low-carbon cementitious materials and geopolymer concrete technologies, examining their fundamental chemistry, mechanical performance, durability, environmental benefits, and barriers to large-scale commercialization. Geopolymer concrete, produced by alkali-activation of aluminosilicate precursors such as fly ash, slag, and metakaolin, demonstrates CO₂ reductions of 40–80% relative to conventional OPC-based systems while achieving comparable or superior compressive strengths (40–120 MPa), enhanced acid and fire resistance, and substantially lower embodied energy. Supplementary cementitious materials (SCMs) including ground granulated blast-furnace slag (GGBS), silica fume, and calcined clays have been increasingly integrated into blended cements, with LC³ (Limestone Calcined Clay Cement) emerging as a particularly scalable low-carbon solution. Despite remarkable technical progress, challenges persist in standardization, long-term durability validation, alkali activator supply chains, and public sector procurement policies. This review critically evaluates current knowledge gaps and charts priority research directions needed to transition low-carbon concrete from niche applications to mainstream infrastructure use.
