Self Healing Concrete (Summary draft 2)
According to an article by Spinks (2015), Hendrik Jonkers, a microbiologist from Delft University, plans to extend the life of concrete. The main aim to reduce global cement production and reduce the maintenance of the current concrete. Although it comes in many forms and has a lifespan of 200 years, it only can heal cracks up to 0.8mm wide and it cost more than the usual concrete. Nevertheless, according to Spinks, John Alker, director of policy at the UK Green Building Council, mentioned that the success of the self-healing concrete depends on Jonker’s ability to demonstrate it. Furthermore, according to Spinks, Jonkers mentioned that this concrete is being tested globally, especially in developing countries, to show that it saves labour despite its cost. Even though this article explains the targets that the self-healing concrete aims to achieve, it is still not robust enough in explaining how this building material is being used in projects globally.
One of the projects that involves self-healing concrete is in Ecuador.
