建筑行业微生物腐蚀与防护研究进展

Research Progress of Microbiologically Influenced Corrosion and Protection in Building Industry

综述了导致混凝土材料和金属材料微生物腐蚀的研究现状,分别阐述了其微生物腐蚀的机理,包括混凝土生物硫酸腐蚀机制、金属微生物腐蚀的经典腐蚀机制和细胞外电子转移机制。概述了现有的建筑行业混凝土和金属材料微生物腐蚀及混凝土改性、制备保护涂层材料、添加杀菌剂等防护方法的研究进展,为后续建筑材料微生物腐蚀机制和防护技术的深入研究提供参考。

This paper focuses on the present research progress of Micro biologically influence corrosion(MIC) problems of concrete and metal materials and especially the relevant MIC mechanisms, including the biological sulfuric acid corrosion mechanism against concrete materials, and classical corrosion mechanisms and extracellular electron transfer mechanism against metal materials. This paper also introduces research progress of MIC protection methods in building industry, including concrete modification,protective coatings and bactericides. This paper might provide a guidance for further research on MIC mechanisms and protective methods against MIC problems in the building industry.
