Abstract

Cement, the principal component in concrete has a significant deleterious impact on the surrounding environment. Bio-concrete is an excellent alternative that is formed of cement. This paper explores the intricate world of concrete including its broad application, developing technological advancements, and environmental effects. It also discusses the rise of concrete with higher compressive strength compared to conventional concrete and its structural impacts, emphasising the need to give design and construction due thought. Bio-concrete highlights Microbial induced calcium‑carbonate precipitation (MICP) as a sustainable concrete production process and lowering the carbon footprint of building. In order to maximise microbiological performance in bio-concrete, we discuss the importance of gene transformation and discuss related experiments. It covers issues pertaining to bio-cementation in order to advance sustainability and environmental wellbeing. Standardized microbial selection and long-term field performance assessments are necessary knowledge gaps for bio-cementation research, with an emphasis on microbial activity and survival under the challenging conditions of concrete. The conclusion highlights the necessity of research on optimization, production scaling, and long-term performance of microbial strains to enhance and expand the uses of bio-concrete, guaranteeing effectiveness and durability.

混凝土革命：揭示生物混凝土的优势和挑战，通过微生物诱导碳酸钙沉淀自愈

水泥是混凝土的主要成分，对周围环境具有重大的有害影响。生物混凝土是一种很好的水泥替代品。本文探讨了混凝土的复杂世界，包括其广泛的应用，发展中的技术进步和环境影响。它还讨论了与传统混凝土相比，具有更高抗压强度的混凝土的兴起及其对结构的影响，强调需要给予设计和施工应有的考虑。生物混凝土强调微生物诱导碳酸钙沉淀（MICP）是一种可持续的混凝土生产过程，可以降低建筑的碳足迹。为了最大限度地提高生物混凝土的微生物性能，我们讨论了基因转化的重要性，并讨论了相关的实验。它涵盖了与生物胶结有关的问题，以促进可持续性和环境健康。标准化的微生物选择和长期的现场性能评估是生物胶结研究的必要知识缺口，重点是微生物在混凝土挑战性条件下的活性和生存。该结论强调了加强和扩大生物混凝土的使用，保证其有效性和耐久性，必须对微生物菌种的优化、生产规模和长期性能进行研究。
