摘要
微生物诱导矿化技术可用于修复混凝土表面缺陷及裂缝,是一项智能化、环保型的技术。针对这一技术,介绍了微生物诱导碳酸钙矿化沉积反应的机理及影响微生物矿化反应的主要因素,并详细介绍了基于微生物诱导矿化的混凝土既有裂缝的修复方法,总结了微生物法在普通混凝土和水工混凝土既有微小裂缝修复中的应用现状、修复效果评价指标以及面临的问题,并对其未来研究方向提出了建议。
Microbial-induced mineralization technology can be used to repair surface defects and cracks in concrete,which is an intelligent and environmentally friendly technology.For this technology,the mechanism of microbial-induced calcium carbonate mineralization deposition and the main factors affecting microbial mineralization reaction were introduced.Additionally,the repair methods of concrete existing cracks based on microbial induced mineralization was described in detail.Moreover,the status and problems of microbial method in the repair of existing micro-cracks were summarized in ordinary concrete and hydraulic concrete.Finally,the application prospect and future research direction were proposed.
