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.

Subject: Self-introductory email   Dear Professor Blackstone, My name is Darren Ho, and I am a year 1 Civil Engineering student in your module. I graduated from Ngee Ann Polytechnic in 2017 with a diploma in Mechanical Engineering. In 2019, I attended a 3-week AutoCAD course organized by the National Trade Union Congress (NTUC) learning hub to refine my AutoCAD skills. After serving my National Service, I helped my father at his own company, which manufacture doors. He got involved in multiple projects such as Mass Rapid Transit (MRT) projects and I had the opportunity to help him with some work related to AutoCAD for three months. This work includes editing and crafting drawings. Furthermore, I also edited the dimensions of the doors in the drawings as well. With this experience, I decided to enrol in this course to learn more about construction and follow my father’s footsteps to get involved in more of these projects to give back to the community. My hobbies include bowling and runn

The importance of communication skills to engineers

  “Communication skills are an essential component in the education of engineering students to facilitate not just students’ education but also to prepare them for their future careers.”      Marc Riemer, Faculty of Engineering, Monash University (2007) My reflection on this statement: It plays an important role is the curriculum of engineering students because they will learn on how to communicate well with people around them in the future, especially when they are in the workforce, where they need to communicate with people of higher seniority. Therefore, it should be included in student's education.

Summary Reader Response Draft 4 (Self- Healing Concrete)

According to Spinks (2015), cement production caused a huge impact to the environment. To tackle this problem, Hendrik Jonkers had come up with an innovative idea to increase the lifespan of concrete and reduce its production. The article also stated the advantages and disadvantages of self-healing concrete and how this concrete is used globally. Even though Rosie Spinks   stated the advantages and disadvantages of the self-healing concrete, it did not sufficiently state how this concrete is used globally, in terms of   where and how is it used. Firstly, Rosie Spinks mentioned did not specify the countries that utilise this concrete. Based on the research I did, I found a number of countries that used this concrete. One of the countries that is utilised this concrete is Ecuador. According to 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 lead to food shortag
