Summary/ Reader Response Draft #3
In the article “The Self-healing Concrete…”, Spinks (2015) introduces the self-healing concrete innovation by Hendrik Jonkers and discusses how it can provide benefits towards industry players. She mentions that the eco-innovation can repair cracks up to 0.8mm by producing self-activating limestone, ultimately lowering maintenance expenses.
The author also mentions that John Alker, director of the UK Green Building Council, asserts that concrete invention will contribute prominently for the construction industry. He believes that eco-innovation will be appreciated when consumers become convinced of the economic and environmental benefits. However, Jonkers claims that adopting his innovation is challenging as consumers find it costly to implement into their projects. Nevertheless, he finds that tropical regions will value green technology and appreciate self-healing concrete. Jonkers explains how Ecuador had benefitted from using self-healing concrete for its canal and irrigation by avoiding maintenance expenses. He then concludes that developing countries are willing to invest in green technology to avoid long-term costs.
While Spinks outlines the advantages and disadvantages of adopting Jonker's innovation, she fails to highlight how the construction industry can gain economic, environmental and social benefits from using the self-healing concrete.
Primarily, Spinks should have addressed the economic benefits of adopting self-healing concrete. Self-healing concrete can now reduce the cost associated with corrosion in concrete. Water filtration induce corrosion in concrete, thus undermining the foundation and reducing its lifespan. Arnold (2011) states that although concrete is highly susceptible to cracking, it remains to be an important material in construction. The incorporation of Jonker’s self-healing concrete into building foundations will enhance the performance and longevity of the infrastructure. Despite its high material costs, it can set a reduction in the whole life-cost of a structure by minimising repairs. “Repairs can be particularly time-consuming and expensive because it is often very difficult to gain access to the structure to make repairs, especially if they are underground or at a great height” (Arnold, 2011). Using its self-curing properties, the self-healing concrete innovation is a cost-effective investment for industry players.
In addition, the article should have emphasised the environmental advantages of implementing self-healing concrete. Its self-curing properties can significantly reduce the demand for concrete production and minimise environmental pollution. Jarvis (2019), asserts that European countries are exploring eco-solutions in ‘every sector of production and technology’ to extenuate climate change and conserve the environment. According to Maddalena and Gardner (Jarvis, 2019), self-healing concrete represents an environmentally sustainable alternative in improving the durability of a building. It minimises the total maintenance including the continual use of concrete. Its capacity to respond to its environmental circumstances makes it a powerful eco-innovation. Eventually, with the implementation of self-healing concrete in buildings, dust output is reduced and pollution mitigated.
Lastly, Spinks should have presented the societal duty in implementing eco-inventions. A society's cooperation and collaboration is important for a successful eco-transition and a universal implementation of eco-technologies. In her article, Alker suggests that innovators ought to persuade buyers of the financial and ecological gains to be widely embraced. However, Van der Woerd (2019) strives to convince his clients to ‘get on board with the technology because “the demand starts with them”.’ This is further supported in the article (The missing piece in Singapore’s green building puzzle, 2019). Eco-innovation involves the cooperation of the entire society from its inception. Its implementation will improve the quality of life thus creating a sustainable future for everyone.
While it seems impossible to achieve a broad acceptance of eco-innovations, developing its benefits will persuade consumers of the efficacy in supporting sustainable alternatives. With rapid urbanisation and industrialisation, the significance and urgency of environmental conservation should be addressed from the environmental, economic and social perspectives.
