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、环保化的技术。介绍了微生物诱导矿化修复的机理,并详细介绍了基于微生物诱导矿化的混凝土缺陷被动修复技术和混凝土裂缝自修复技术。分析了微生物修复材料与水泥基材料的交互作用,总结了微生物自修复混凝土裂缝的效果。在此基础上展望了其发展趋势,并对该技术在水利水电工程中的应用前景和进一步的研究方向提出了建议。
Microbial-induced mineralization technique is an intelligent and environmental friendly technology, which can be used to repair the concrete surface defects and cracks. Recent development on the mechanisms of microbial-induced mineralization, passive repair and self-healing technology is reviewed in this paper. The interaction between microbial repairing materials and cementitious materials is analyzed, and the effectiveness of microbial-induced self-healing of concrete cracks is summarized.Furthermore, the development prospects are discussed and recommendations for the future development of microbial-induced repair technique are presented.
