Deterioration of concrete durability is accelerated via penetration of moisture and chemicals into microcracks and pores [1]. Microbial biocalcification is a feasible method for repairing microcracks in concrete, thereby yielding fillers for cracks and pores in concrete. The self-healing technology using microbial-induced calcium carbonate (CaCCb) precipitation (MICCP) is an economic and innovative method to satisfy both durability and environmental demands. Numerous studies on self-healing concrete using microbes performing MICCP isolated from soil have been actively carried out; however, few studies have investigated self-healing concrete in a marine environment. This study reviews previous studies on self-healing concrete, based on bacterial biocalcification. A portion of a feasibility study [8] on identifying bacteria capable of MICCP in a marine environment to be used in self-healing concrete material will be also presented.
