Concrete is the most commonly used material of numerous structures around the world due to resistance, durability and low cost compared with other construction materials. However, traditional construction materials are susceptible to suffer deterioration by physical, chemical and biological factors that produce irreversible damage to their structure, which requires a high-cost of repair and maintenance. Additionally, during production process cement industry emits about 0.73 – 0.99 t CO2/ t of cement produced. Bioconcrete is emerging as an ecological, economical and sustainable alternative for construction industry. Biomineralization by bacteria facilitates the development of bioconcrete, wherein calcium carbonate is formed by the metabolic activity of microorganisms, which involves a series of complex reactions directed mainly by urease and carbonic anhydrase enzymes. In this review, biomineralization processes involved in bioconcrete formation and their potential use for the construction industry is discussed.
