The Secret to Super Strong Concrete Is... Bacteria?

The video explores the potential of bacteria to revolutionize concrete by enabling it to self-repair. Concrete, a widely used material, faces issues like cracking and environmental impact due to cement production. Scientists have discovered bacteria that can survive in concrete's alkaline environment and excrete calcite to fill cracks. This self-healing concrete can restore over 90% of its strength but is currently expensive. Future research aims to reduce costs and expand its use in challenging environments.

How do bacteria contribute to the self-repairing process of concrete?

What are the potential future applications of bacteria in concrete as mentioned in the text?
