Summary Reader Response (Draft 2) - Self healing concrete
According
to an article “The Self-healing Concrete That Can Fix Its Own Cracks” Rosie
Spinks (2015), she mentioned about the environmental impact that cement
production can cause. To tackle this problem, Hendrik Jonkers had came up with
an innovative idea to increase the lifespan of concrete and reduce its
production. The article also stated about the advantages and disadvantages
about the self-healing concrete and how this concrete is used globally. Even
though this article did state about the advantages and disadvantages of the
concrete, it did not sufficiently state on how this concrete is used globally,
like where and how is it used?
Firstly, the article mentioned that this concrete is used
in Ecuador. Based on the article “Self-healing irrigation canals in
Ecuador.” Van Dijk (2014), a concrete canal in the Andean highlands is
facing problems due to constant changes in temperature. As a result, cracks
were formed in the canal and it leads to food shortage and crop failure to the
surrounding communities due to water leaks in it. Self -healing concrete was
used in the canal, in which the purpose was to repair the cracks in it and reduce
time and cost to change parts in the canal.
Secondly,
another country that is utilizing this concrete is India. Based
on the article “Self-healing roads protecting
villages in India from heavy rains.” Ong
(2016), Dr Menkumar Banthia, an engineering professor at the
University of British Columbia (UBC), stated the road in Thondebavi,
Southwestern India, was inaccessible by car or foot and people depend on this
road to do their daily activities. The road was revamped with strong self-healing
concrete. With this innovation, the road is stronger and also has the ability
to repair its own cracks when rain is present. As a result. this makes it more
accessible for the residents around the vicinity. Both above mentioned articles
shows that the renovation of public facilities using self-healing concrete has a
positive impact on people’s daily lives.
Thirdly,
another country that is utilizing this concrete is the Netherlands. In the article
“Self-Healing Concrete in The Netherlands.”
Williams (2017), a water utility centre plans to invent water storage tanks that is made
partially with self-healing concrete. The reason is that the centre intends to
reduce the time and cost of changing parts in the tanks whenever there are any
faulty ones. This article shows that self – healing concrete used in water
plants is effective. As the water contain a massive number of bacteria, it produces limestone which in turn can heal the cracks in the water tank.
Although
the characteristics of the concrete is mentioned. I believe that if the article
mentioned about some countries using this concrete, we can understand how it
helps in that particular country. That way I believe that other countries can
be inspired by these projects and be more innovative in the future.
