Researchers from Delft Technical University in the Netherlands have developed concrete that can heal itself using special bacteria.
Repairing cracks in concrete structures
, which usually happen when tension is applied to it, is a time consuming, costly but necessary business. Jonkers and Schlangen added a harmless bacteria known as Bacillus genus to the concrete which remained dormant until rainwater entered the cracks which occur naturally inside concrete. The bacteria used the nutrients the researchers incorporated into the cement (calcium lactate – a component of milk).
