Review on the potential application of bacterial cementitious composites in Indonesia

Abstract

Cementitious composites are common construction material for infrastructures. Their abundant resources are one of the reasons why they are widely consumed. The drawback of these materials is its brittle nature resulting in unavoidable cracking problems in the infrastructures. Further, the crack will initiate the corrosion of steel reinforcement and reduce structural durability. Calcium carbonate precipitating bacteria are the potential to heal the cracks in the cementitious composite if they are selected and treated carefully. This paper reviews different types of bacteria applied in concrete, and the methods can be used as a healing agent. This study recommends using bacterial cementitious composites as self-healing material, surface treatment, and crack healing agent.
