摘要

近年来胶凝复合材料的生物混凝土技术为我们带来了微生物在具有自愈能力的混凝土材料上的应用。某些微生物,如细菌、藻类和真菌,已经被确定能够提高混凝土的强度和其他性能,包括耐久性、抵抗力、自我修复等。这些微生物的关键能力是它们诱导方解石生物矿化的能力,这也被称为微生物诱导的碳酸钙沉淀。这种能力使微生物能够在特定的生化反应下产生方解石,类似于水泥混凝土中的粘合材料,从而提高混凝土的性能,并在进一步扩展之前修复微裂缝。然而,每种微生物都有自己的特点,考虑到反应物、产物、可用性、生存能力、可持续性等,这给其应用带来了一定的挑战和好处。尽管在这一领域已经进行了许多研究,但不同的研究结果之间的微生物、培养、处理、测试方法和获得的结果各不相同。本文揭示了不同类型微生物的基本和最新的生物混凝土发现。

Microbes in bioconcrete technology: exploring the fundamentals and state-of-the-art findings for advancing civil engineering
ABSTRACT The bioconcrete technology on cementitious composites over the past years has brought us the application of microbes on concrete materials with self-healing ability. Certain microbes, such as bacteria, algae, and fungi, have been identified as able to enhance the strength of concrete and other properties, including durability, resistance, self-healing, and others. The key ability of those microbes is their capability to induce calcite biomineralization, which is also known as microbiologically induced calcium carbonate precipitation. This ability allows microbes to produce calcites under specific biochemical reactions comparable with the bonding material in cement concrete, thus enhancing concrete properties and healing microcracks before further propagation occurs. However, each microbe has its own characteristic that brings certain challenges and benefits to its application, considering the reactants, products, availability, survivability, sustainability, etc. Although many studies have been done in this field, the microbes, cultivations treatments, testing methods, and obtained outputs vary between one finding and another. This paper discloses both the fundamental and state-of-the-art bioconcrete findings for different types of microbes.
