Self-Healing Of Concrete or Bio Concrete to Repair Cracks

It is mainly used in heavy construction because of its strength and durability. No matter how carefully the concrete is mixed or reinforced it eventually ends up in cracking at some point. There are many factors that affect the durability and strength of concrete, one of the most common hindrances is crack formation. Large cracks may affect the structural integrity while small cracks reduce the durability of the structure. In order to reduce the chances of crack formation a structure requires regular maintenance which can be costly and may further increase the maintenance cost of the structure. One way to reduce such costs and increase the durability of the structure is to use concrete that has a self-healing mechanism. Concrete is a very good material to resist compressive load to a limit but if the load applied on the concrete is more than the limit of resisting load, it causes the strength reduction of concrete by producing cracks in the concrete, and the treatment of the cracks is very expensive. Due to the increase in the permeability of the concrete, the water easily passes through the concrete and meets the reinforcement of the concrete structure after some time corrosion start due to this strength of the concrete structure will decrease so it will be necessary to repair the cracks.
