Summary/Reader Response Final Draft: Concrete That Grows (b)
Scientists create living concrete from bacteria and sand According to the article written by Corless (2020), "Scientists create living concrete from bacteria and sand", researchers from the University of Colorado Boulder have created living concrete from bacteria and sand. They have introduced a new living material, by combining sand, hydrogel and bacteria. Corless explains that photosynthetic cyanobacterium was biomineralized with a 3D sand-hydrogel scaffold, which produces new bricks from the original brick. The article also claims that biological viability and mechanical performance cannot coincide. Thus, additives are incorporated to enhance the quality of the material. Hence, it possesses properties that are comparable to cement-based mortar, which carries biological purposes. Corless interviewed the director of Living Materials Laboratory, who claimed that this process would change people's thinking about the manufacturing industry and reusable materials. C
