摘　　要：综述了纳米蒙脱石对混凝土力学性能和耐久性影响的研究。研究表明,纳米蒙脱石的加入可显著提高混凝土的抗压、抗拉和抗弯强度,同时改善抗渗性、抗冻性和抗腐蚀性能。这主要归因于其填充效应、火山灰效应和成核效应。然而,过量使用可能导致材料强度下降,未来研究应集中在优化使用方法、深入研究其作用机制、改进分散技术,以及验证纳米蒙脱石改性混凝土在实际工程中的性能和效果。Research has shown that the addition of nano montmorillonite can significantly improve the compressive,tensile and flexural strength of concrete,while also improving its impermeability,frost resistance and corrosion resistance.This is mainly attributed to its filling effect,volcanic ash effect and nucleation effect.However,excessive use may lead to a decrease in material strength,and future research should focus on optimizing usage methods,delving into their mechanisms of action,improving dispersion techniques and verifying the performance and effectiveness of nano montmorillonite modified concrete in practical engineering.
