建筑材料中的生物胶结:综述
摘要
用于建筑用途的粘土砖的大量生产加剧了这个问题。这种情况导致其生产过程中的高能耗和碳排放。在这方面,生
物水泥被认为是建筑施工的绿色解决方案,因为这种技术对环境友好,能够减少碳排放,从而减缓全球变暖速度。
大多数先前发表的文章都集中在微生物诱导的碳酸钙沉淀(MICP)上,其生物胶结的机制与尿素水解的发生有关,
这是微生物的脲酶酶活性产生铵离子和碳酸根离子的结果。然后这些离子将在有利条件下与钙离子反应以沉淀碳酸
钙。MICP被研究用于裂缝修复和各种建筑材料的表面处理。研究用于生产建筑材料粘合剂的MICP已成为建筑工程
的最新趋势。随着前沿MICP研究的发展,本文有利于回顾MICP在建筑工程中的最新趋势,从而全面了解微生物在
生物水泥中的利用。
