Self-Healing Concrete Summary Draft 1

According to an article by Spinks (2015), cement production contributed to 8% of total global emissions. To tackle this issue, microbiologist Hendrik Jonkers, from Delft University, plans to extend the life of concrete. With that in mind, he invented the self-healing concrete, which involves two fields: Civil Engineering and Marine Biology. However, for it to work, bacteria from rainwater or atmospheric moisture must be present. The reason is that it produces limestone to repair the cracks. The cost is more expensive than the normal one, so the cost of building essential infrastructure will be increased. Although it comes in many types, it only can heal cracks up to 0.8mm wide. With Jonkers able to demonstrate a product’s benefit, he pointed out that coastal communities and tropical regions would benefit from this concrete. Furthermore, he mentioned that it is tested in developing countries to profit from this concrete.

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
