摘要
自愈合防水混凝土包括水化反应型、微胶囊机制、微纤维机制和微生物等类型,文章重点介绍了微生物自愈合防水混凝土的作用原理,并通过试验测试了含有巴氏芽孢杆菌的微生物自愈合防水混凝土对裂缝的修复效果.结果表明,含有巴氏芽孢杆菌的微生物自愈合防水混凝土可通过细菌诱导生成碳酸钙沉淀封堵裂缝,在裂缝自愈合性能方面远超普通混凝土.
Abstract
Self-healing waterproofing concrete includes hydration reaction type,microcapsule mechanism,microfiber mechanism and microorganisms etc.This article focuses on the principle of microbial self-healing waterproofing concrete and tests the repair effect of microbial self-healing waterproofing concrete containing Bacillus subtilis on cracks through experiments.The results indicate that microbial self-healing waterproofing concrete containing Bacillus subtilis can induce the generation of calcium carbonate precipitation through bacteria to seal cracks,and its self-healing performance is far superior to ordinary concrete.
