Concrete is one of the most broadly used construction materials in the world due to its number of performance characteristics. Despite the long life of concrete structure under ideal conditions, it tends to crack and this phenomenon results in a considerable reduction in service life and performance. Evidence of microbial involvement in the precipitation of minerals has led to a massive investigation on adapting this technology for addressing the concrete cracking issue. Calcium carbonate is one of most compatible materials with the concrete constituents and it can be induced via biological process. In this review paper, the effects of different factors, such as nucleation site, pH, nutrient and temperature, on the biosynthesis of calcium carbonate are elucidated. Moreover, the influences of effective factors on calcium carbonate polymorphism are extensively elaborated. Finally, the limitations for the future application of this innovative technology in construction industry are highlighted. [GRAPHICS] .
