Self-healing Concrete Summary Draft 2

-

In the article, “The Self-healing Concrete That Can Fix Its Own Cracks”, Spinks (2015) narrated an innovation that Jonkers invented which was embedding self-activating bacteria into concrete to make it self-healing. He stated that the bacteria can exist for up to 200 years as long as particles exist for it to feed on, and also mentioned that the bacteria will start producing limestone to repair the cracks when water starts seeping into the cracks. He also noted that the self-healing concrete was unable to repair  large cracks, and only capable in repairing cracks up to 0.8mm wide. According to Jonkers, a cubic meter of concrete cost €70, while the self-healing concrete cost €100. Nonetheless, Jonkers remarked that some countries with coastal communities or tropical regions with extreme rainfall are seeing the cost-benefit analysis of using the self-healing concrete. It was concluded by Jonkers that these tests were done in developing countries where they see profits in the future. While the article gave some information about the self-healing concrete, it should also mention the viability of it being used in construction of buildings.

Self-Introduction Letter

Subject: Self-Introduction Email Dear Professor Blackstone My name is Amos Bian, and I am currently studying civil engineering in Singapore Institute of Technology (SIT) as a year 1 student. Before enrolling into SIT, I graduated Nanyang Polytechnic with a diploma in engineering with business. Being a son of a project manager, I grew up listening to my father talk about the projects he had undertaken. Those discussions sparked my interest in his job, and it resulted in me wanting to become like my father. I have taken up leadership roles in both army and secondary school in the past which made me more comfortable in speaking. As a leader, there is a need for me to communicate with my superiors and my subordinate on various instructions given while ensuring that it is clear, and this made me become more outspoken as a person. However, I do have a tendency to stutter which will cause confusions, and this resulted in it being unorganized and rushed at times. Being in this course, I wo...

Importance of communication skills for 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 thoughts: Communication skills is a necessity for engineering students' education as it plays an important role in their future careers. For example, being able to communicate with clients or pass information around requires good communication skills. Hence, communication skills should be part of an engineering students' education.
