Concrete microorganism self-repairing method suitable for saline-alkali environment
The invention provides a concrete microorganism self-repairing method suitable for a saline-alkali environment. Comprising the following steps: attaching microbial spores, a nutritional agent and a mineralizing agent to the surface of a porous carrier; microbial spores, a nutritional agent and a mineralizing agent are implanted into the concrete through a porous carrier, and the concrete is self-repaired after cracking in a saline-alkali environment. According to the method disclosed by the invention, the limitation of a saline-alkaline environment on a concrete microorganism self-repairing technology can be broken through by implanting the saline-alkaline tolerant urease-producing bacterial spores, the nutritional agent and the mineralizing agent into the concrete, so that the aim of self-repairing cracks of the concrete in the saline-alkaline environment is fulfilled; the application range and the repairing efficiency of the concrete microorganism self-repairing technology are greatly expanded.
本发明提供了一种适用于盐碱环境的混凝土微生物自修复方法；包括以下步骤：将微生物芽孢、营养剂和矿化剂附着于多孔载体表面；通过多孔载体将微生物芽孢、营养剂和矿化剂植入混凝土内部，混凝土在盐碱环境中开裂后实现自我修复。本发明所涉及的方法通过将耐盐碱产脲酶细菌芽孢、营养剂和矿化剂植入混凝土，能够突破盐碱环境对混凝土微生物自修复技术的限制，实现混凝土在盐碱环境裂缝自我修复的目的，极大地拓展了混凝土微生物自修复技术的应用范围和修复效率。
