What is bacterial concrete? Which are the area of application of bacterial concrete?

Bacterial concrete is a construction material that fills up the cracks developed in structures with the help of bacterial reaction in the concrete after hardening.

hmmm thanx for your responce

Bacterial concrete is a self-healing concrete that automatically repairs cracks and makes the structural member structurally sound again. In bacterial concrete, dormant bacteria, along with lime and calcium-based nutrient (generally calcium lactate), are added into the concrete. When there’s a crack greater in width than the micropores already present, it takes in water. The water germinates the bacteria, which then starts feeding on the calcium lactate, making lime. Lime reacts with water to give calcium hydroxide. Calcium hydroxide slowly reacts with atmospheric carbon dioxide to give calcium carbonate (limestone). This limestone permanently repairs the crack.
Bacterial concrete has also shown a higher compressive strength and reduced permeability after action.
Although it isn’t yet a traditional practice to the use bacterial concrete in some specific applications, it can be useful in :

Bacterial concrete is also known as Bio concrete or Self healing concrete, which is invented under the head of Henk Jonkers.
It resists the alkalinity and mechanical stress in concrete.
Generally Cohnii and Filla bacteria are used for making this type of concrete.
Application of Bacterial Concrete:-
It is used for increasing concrete durability and life span of the structure by self-healing of cracks in the structure.
