Summary Draft 2 - "The Self-Healing Concrete..."
In the article “The Self-Healing Concrete…” Spinks (2015), Spinks shares a new green technology by Hendrik Jonkers, a microbiologist at Delft University. His innovation increases the lifespan of concrete by embedding self-activating limestone-producing bacteria into building material.
Jonkers hopes to decrease production of new concrete and lower maintenance as well as repair costs of essential concrete infrastructures. His innovation comes in three forms: a spray, a repair mortar and the self-healing concrete itself. He predicts that this new green technology will be especially useful in highway infrastructure. Although this new green technology sounds promising, Spinks mentions that it cannot cure cracks wider than 0.8mm. John Alker, director of policy at the UK Green Building Council, believes that a breakthrough for this technology will be tough and it is up to clients and developers’ willingness to test it and prove its usefulness before others will follow. Jonkers’ innovation has been used for a concrete irrigation system project in Ecuador and is being tested in developing countries all over the world. In view of the fact that this new self-healing concrete technology comes in three convenient forms, it will be potentially lucrative for the construction industry especially in a concrete jungle such as Singapore.
