Summary draft #1 : Self-healing concrete

In the article, “The Self-Healing Concrete That Can Fix Its Own Cracks,” Spinks (2015) stated that Hendrik Jonkers’ innovation is to “decrease the amount of new concrete produced, lower maintenance and repair costs for city officials, building owners and homeowners” by inlaying self-activating limestone-producing bacteria into concrete. The self-healing concrete has longevity of up to 200 years and helps to reduce carbon emitters. However, it can only repair up to 0.8mm wide of cracks and cost  €30 more than normal concrete. Regarding this, Alker believes that it will be hard to convince the industry to adopt the new innovation. It will take unconventional consumers and developers who are willing to test their building with the new concrete to demonstrate positive results before others will tag along. Jonker has been experimenting across the world where he claims that the people realized the profit because they can save up on the maintenance.

Self-introduction email

Subject: Self-introduction email Dear Professor Blackstone I am writing this email in hopes that you will understand me better and improve my weaknesses in communication. My name is Lin Yi and I am currently an undergraduate studying civil engineering at the Singapore Institute of Technology (SIT). Prior to this, I graduated with a diploma in the same course at Singapore Polytechnic. I furthered my studies in the course as it is my way of giving back to society. Engineering in the modern world is no longer solely plan and build, we also improve the way people live and work. As such, I feel that communication is essential to achieve that.  Different styles of communication are needed for different types of audiences. One of my strengths in communication would be adapting my communication style to the differing types of audiences. As a leader in my CCA in secondary school, I had to liaise with different groups of people. This skill allows me to maximize the impact and get my point across

In the article, “The Self-Healing Concrete That Can Fix Its Own Cracks,” Spinks (2015) states that Hendrik Jonkers created self-healing concrete innovation to “decrease the amount of new concrete produced, lower maintenance and repair costs for city officials, building owners and homeowners” by inlaying self-activating limestone-producing bacteria into the concrete. The self-healing concrete has a longevity of up to 200 years and helps to reduce carbon emitters. However, the concrete can only repair up to 0.8mm wide of cracks and cost €30 per metre cube more than normal concrete. According to Alker, who is director of policy at the UK Green Building Council, it will be hard to convince the industry to adopt the new innovation. It will take unconventional consumers and developers who are willing to test their building with the new concrete to demonstrate positive results before others will support it. Jonker has also been experimenting across the world where he claims that the people re

The Importance of Communication Skills for engineers

 "Employers identify communication as one of the basic competencies every graduate should have, asserting that the ability to communicate is valuable for obtaining employment and maintaining successful job performance."  Sherwyn Morreale, Michael Osborn & Judy Pearson, Professors of Communication (2000) Communication skill is one of the most fundamental and important skill everyone should adopt, this explains why graduates are expected to have it before entering the workforce. It is essential in our everyday life, be it passing on information or liaising with your colleagues. Effective communication will allow better productivity in the workplace and prevent conflicts from arising.
