Anaerobic microorganism self-repairing concrete and preparation method thereof
The anaerobic microorganism self-repairing concrete comprises the following components in percentage by mass: 0.07%-0.10% of a bacterial repairing agent; and 28.88%-29.76% of a cementing material. 0.66%-0.79% of a reinforcing agent; 62.74% to 63.81% of aggregate; 0.29%-0.36% of a water reducing agent; 6.25%-6.29% of water; according to the self-repairing concrete formula, a microcapsule technology is adopted as a carrier to carry microbial colonies and part of substances required by self reaction to prepare concrete, when the concrete begins to crack, the microcapsule structure is damaged and released, anaerobic bacteria carried in the carrier generate urease, and the self-repairing concrete is prepared. Urea in the poured concrete is hydrolyzed and then is subjected to a calcification reaction with Ca < 2 + > in the concrete, so that the effect of repairing the cracks is achieved; and cracks can be reduced, the concrete which begins to be damaged can be used for a longer time, and the integrity of the concrete is maintained.
一种厌氧微生物自修复混凝土，包括质量百分比为：细菌修复剂0.07％‑0.10％；胶凝材料28.88％‑29.76％；强化剂0.66％‑0.79％；骨料62.74％‑63.81％；减水剂0.29％‑0.36％；水6.25％‑6.29％；本发明自修复混凝土配方中，采用了微胶囊技术作为载体携带微生物菌落和其自身反应所需的部分物质，制作混凝土，当混凝土开始出现裂缝时，微胶囊结构发生破坏释放，载体中载有的厌氧菌通过生成尿素酶，经浇筑混凝土内部的尿素水解后与混凝土中的Ca2+进行钙化反应，从而达到修补裂缝的效果；能够减少裂缝的产生，并使开始破坏后的混凝土能维持更长的使用时间，以及维护混凝土的整体性。
