摘　　要：盐渍土地区的混凝土结构常受到特殊腐蚀问题的困扰,影响其耐久性和长期稳定性。本研究深入分析了盐渍土对混凝土的腐蚀机制,揭示了其腐蚀性物质如何影响混凝土性能。通过实验室模拟与现场取样,准确评估了混凝土在此环境下的变化。利用非破坏性检测技术,我们高效地监测了腐蚀进程。原材料选择方面,本文特别强调了低碱水泥的应用价值,通过对比不同水泥品种,为工程实践提供了决策参考。Concrete structures in saline soil areas are often troubled by special corrosion problems,which affect their durability and long-term stability.In this study,the corrosion mechanism of saline soil on concrete is deeply analyzed,and how its corrosive substances affect the performance of concrete is revealed.Through laboratory simulation and field sampling,the concrete changes in this environment were accurately evaluated.Using non-destructive detection technology,we effectively monitored the corrosion process.In terms of raw material selection,this paper emphasizes the application value of low-alkali cement,and provides decision-making reference for engineering practice by comparing different cement varieties.
