随着微生物矿化修复混凝土技术的发展,研究将微生物修复剂内置于混凝土基体中,以达到"主动修复"的效果具有重要的实际意义.本文回顾了近年来具有代表性的内置微生物修复剂诱导矿化生成无机盐修复技术在混凝土裂缝修复中的研究成果和进展,探讨了内置微生物修复剂诱导矿化生成无机盐修复技术存在的问题和工程应用研究前景,最后指出了内置微生物自修复材料修复技术有待于解决的主要问题.评述表明:目前内置微生物自修复材料修复技术仍停留在实验室研究阶段,真正用于工程较少,须积极寻求其它低廉、对施工条件要求低的微生物载体.
With the development of the use of a biological healing cracks technique, to study building the microorganism healing agent into concrete to carry the point of concrete healing positively is of great practical significance.This paper reviewed some research achievements and progress of typical building the microorganism healing agent into concrete to inducing generating mineral salt healing cracks technique, discussed the existing problems and engineering application research prospect of healing cracks technique.Finally the main problems to solve built-in microbial self-healing material repair technology were pointed out.The review shows that: the self-healing materials and technology are still in the research stage of the lab, so it is really used less in the engineering, so it is necessary to seek other low-cost and low-requirement microbial carriers.
