摘要

胶凝材料的自愈可以通过酶解尿素沉淀碳酸钙来实现。当水泥出现裂缝时，可以通过让细菌接触从裂缝中渗出的水来修复损坏。这就形成了碳酸钙，可以修复裂缝。这是因为微生物开始代谢和沉淀矿物质，愈合裂缝造成的损害。然后，将细菌放入各种容器中，这些容器通过破碎释放出微生物，导致碳酸钙的沉淀。此外，本文还引用了用于自修复的高吸水性聚合物(SAP)和最近开发的最先进的胶凝材料自修复技术——有机-无机核-壳复合聚合物(SAP)。

Self-Healing Cement: A Review

The self-healing of cementitious materials can be achieved by precipitation of calcium carbonate through the enzymatic hydrolysis of urea. When a crack appears in cement, the damage can be repaired by allowing bacteria to encounter the water seeping through the crack. This forms a calcium carbonate, which heals the cracks. This occurs because microorganisms begin metabolizing and precipitating the mineral, healing the damage caused by the crack. Then, bacteria are incorporated into various containers, which release microorganisms by crushing, leading to the precipitation of calcium carbonate. In addition, this paper references the superabsorbent polymers (SAP) used for self-healing and hybrid organic-inorganic core–shell SAPs, a recently developed, state-of-the-art self-healing technology for cementitious materials.
