Concrete has one major drawback. Cracks can easily form under pressure. If such cracks become too large, this will lead to rust of the steel reinforcement. Such concrete rot is at the expense of the sturdiness of the structure. It would be ideal if the concrete were self-healing, and that is what the TU Delft researchers are currently working on.
By incorporating calcium-producing bacteria into the concrete, it should be possible to make concrete with such self-healing properties. Prof. dr. Henk Jonkers of TU Delft has been looking for bacteria that are suitable for this. With his research he has found three types that can be used in self-repairing concrete.
Speaker
