Self-Healing Concrete Summary Draft 1
According to an article by Spinks (2015), cement production contributed to 8% of total global emissions. To tackle this issue, microbiologist Hendrik Jonkers, from Delft University, plans to extend the life of concrete. With that in mind, he invented the self-healing concrete, which involves two fields: Civil Engineering and Marine Biology. However, for it to work, bacteria from rainwater or atmospheric moisture must be present. The reason is that it produces limestone to repair the cracks. The cost is more expensive than the normal one, so the cost of building essential infrastructure will be increased. Although it comes in many types, it only can heal cracks up to 0.8mm wide. With Jonkers able to demonstrate a product’s benefit, he pointed out that coastal communities and tropical regions would benefit from this concrete. Furthermore, he mentioned that it is tested in developing countries to profit from this concrete.
