摘　　要：混凝土容易产生裂缝影响其耐久性,传统的修补法价格昂贵且效果一般,而微生物矿化修复裂缝技术具有较大的应用潜力。从固载方式和机理、载体材料及效果,存在问题和未来展望4个方面对近年来的微生物载体材料研究进行论述。微生物载体对激活芽孢形成营养细胞进行代谢,为芽孢提供营养物质以及混凝土抗压强度的影响较大,载体类型的探索具有很高的研究价值和应用前景。Concrete is easy to crack and affect its durability.The traditional repair method is expensive,and the effect is general,but the microbial mineralization repair technology has great application potential.This essay reviews the research progress of microbial carrier materials in recent years from four aspects immobilization mode and mechanism,carrier materials and effects,existing problems and future prospects.Microbial carriers have great influence on the metabolism of activated spore forming nutrient cells,providing nutrients for spores and compressive strength of concrete.The exploration of carrier types has high research value and application prospect.
