摘要
混凝土是国家基础建设的重要工程材料,然而由于服役环境的复杂性,混凝土面临微生物腐蚀造成的劣化问题,给各行业发展和设施安全运行带来了安全隐患和经济损失,因此对混凝土的防护尤为重要.简要介绍了混凝土材料的应用现状和微生物腐蚀混凝土材料的机理,针对微生物腐蚀混凝土的方式,详细综述了目前保护混凝土免受微生物腐蚀的4种主要方法.重点讨论了微生物灭活、混凝土改性、涂层和生物矿化阻止微生物腐蚀的原理和研究进展,列举了不同方法抵抗微生物腐蚀的案例,总结了4种方法存在的优缺点;并且通过综述已有的混凝土防护方法,展望了未来微生物腐蚀混凝土的防护方法研究方向.
Abstract
Concrete is an important engineering material for national infrastructure construction.However,due to the complexity of the service environment,concrete faces the problem of deterioration caused by microbial corrosion,which brings safety hazards and economic losses to the development of various industries and the safe operation of facilities.Therefore,the protection of concrete is particularly important.In this paper,the application status of concrete materials and the mechanism of microbial corrosion of concrete materials were introduced.According to the ways in which microorganisms corrode concrete,the four main methods of protecting concrete from microbial corrosion were reviewed.Meanwhile,the principles and research progress of microbial inactivation,concrete modification,coatings and biomineralization in preventing microbial corrosion were discussed in detail.Cases of different methods used to resist microbial corrosion were presented,and the advantages and disadvantages of these four methods were summarized.Furthermore,by reviewing the existing concrete protection methods,the future research direction of protection methods for concrete against microbial corrosion was prospected.
