Review: Microbial induced mineralization of calcium carbonate for self-healing concrete

Abstract

Abstract. Elkhateeb WA, Elnahas MO, Daba GM. 2021. Review: Microbial induced mineralization of calcium carbonate for self-Healing concrete. Asian J Nat Prod Biochem 19: 1-9. Low-cost solutions achieving concrete self-healing are attracting researchers’ attention. Generally, a concrete self-healing mechanism has been accomplished so far by three approaches: autogenous healing, encapsulation of polymeric material, and microbial-induced mineralization of calcium carbonate. The microbial approach seems an attractive, potent, and relatively cheap way to achieve concrete self-healing. Hence, this review elucidates the microbial concrete self-healing mechanisms and compares the roles of fungal and bacterial mediated self-healing concrete.
