Biomineralization refers to the process by which living organisms produce minerals to harden or stiffen the existing tissues. When applied to the field of cement and concrete, biomineralization involves the use of biological processes to deposit minerals within the material matrix, enhancing its mechanical properties and durability. This technology is inspired by natural processes like those observed in seashells or bone, where organisms deposit calcium carbonate or phosphates to create hard, durable structures. In the context of concrete, biomineralization is harnessed to precipitate calcite and other minerals within the pores of the material, leading to improved strength, reduced porosity, and increased resistance to environmental degradation. This approach not only enhances the material’s performance but also contributes to sustainability by potentially reducing the need for synthetic chemicals and lowering carbon emissions associated with traditional cement production.
