裂缝的存在会使混凝土性能逐渐退化,因此进行裂缝修复具有重要意义。基于微生物诱导碳酸盐沉淀(MICP)的自修复技术作为一种环境友好、长期可行的修复方法而备受关注。在自修复体系中,微生物矿化沉积能力直接决定自修复的效果,而载体则充当微生物“保护壳”的作用,为其新陈代谢提供足够的空间,载体材料的使用显著提高了微生物抵抗恶劣环境的能力,确保自修复效果的实现。本文评述了目前国内外应用于微生物自修复混凝土体系中载体材料的研究成果。对微生物自修复混凝土的工作机理进行阐述与总结,对多孔类载体、闭合类载体、纳米材料载体以及菌群自身充当载体等不同载体材料的研究进展进行了讨论与对比,分析了载体材料的专利转化以及工程应用,并指出当前存在的问题。最后,展望了载体材料在微生物自修复混凝土领域的应用前景,旨在为该技术的应用提供一定的指导和建议。
