Abstract

With urbanization expansion, application of concrete and construction materials is widely increasing throughout the world. Therefore, the use of a mechanism that can effectively extend the life of concrete structures is essential. Durable reinforced concrete structures are generally affected by the crack. Cracks in concrete are caused due to various reasons such as an environmental attack, overloading or accidental damage. Surface cracks in concrete facilitate the penetration of chemicals and corrosive chlorine, so as a result of these factors steel rebars corroded and caused the destruction of concrete structures. Calcium carbonate precipitates have proved their ability as a microbial sealant to fill the cracks and the gaps in Granites and sand. In this method, urea is hydrolyzed by the urease secreting bacteria and calcium carbonate is formed in the presence of calcium ion, which improves the stability and properties of concrete in the long term. Therefore, the use of microbial precipitation in concrete restoration can be considered as a natural and environmentally friendly strategy. This paper reviews current progress and potential of this technology.
