Draft # 1 Summary

     In the article, "The Self-healing Concrete That Can Fix Its Own Cracks", Spinks (2015) discusses how the construction industry will benefit from self-healing concrete (SHC). Hendrik Jonkers, the inventor states the invention can reduce maintenance fees by optimizing the lifetime of the concrete. The research from HealCON observes the maintenance of cracked old-fashioned concrete for essential infrastructure in the EU costs 6bn (4.2bn) yearly. She notes that SHC can mend up to 0.8mm cracks of the existing structure. However, she remarks a cubic meter of self-healing concrete is 30 dollars more expensive than concrete. Jonkers mentions that he successfully constructed a canal and drainage system by the invention. This can be a successful record to convince the built industry. He believes that “coastal communities” can benefit from it. He concludes that SHC can be a game-changer for the future of risk-taker investors in the construction field.
