【摘要】 混凝土其最大的缺点是表面及内部容易产生微裂缝。微生物诱导碳酸盐沉积被认为是一种有效的微生物修复混凝土的策略,目前已逐渐引起人们的关注。在阐述了混凝土裂缝自修复机理的基础上,对近年来利用微生物的碳酸盐沉积作用修复混凝土方面的研究现状和成果进行了系统的综述,并对未来该领域有待解决的一些问题提出建议。更多还原

【Abstract】 As the extensively used construction material,the main drawback of concrete is its liabilityto crackingon the surface and inside.Bacterially induced carbonate precipitation has been proposed as an effective way to heal the crack and aroused broad concern gradually.The mechanism of bacterially induced self-healing of concrete was elucidated,and recent research including strains,substrates and influential factors on concrete healing process was summarized.Furthermore,some potential problems existing in the field were analyzed and the way to solve these problems was suggested.更多还原
