Arnold, D. (2011). Articles - Self-Healing Concrete. Retrieved 6 March 2020, from https://www.ingenia.org.uk/Ingenia/Articles/eb2f64de-2493-4dfc-9adc-3ae8e13ca477 The focal point of this article was the progression of 'self-healing' concrete technology over the years. According to the article 'self-healing' concrete is a mixture of concrete containing 'self-healing' agents such as bacteria and nutrients. The idea of incorporating 'self-healing' agents into concrete mix design of the buildings had been conceived in the late 1900s. However, the idea was not fully realized due to the absence of interest from the ‘commercial engineering sector’. Fortunately, the idea was revived in the early 2000s when numerous notable ‘industry players’ made a partnership with Delft University to further the research and development of self-healing concrete. The pursuit of finding a suitable self-healing agent started in 2006 at Delft University. It was discovered t...

Technical Report Draft #1

Implementing self healing bacterial medium in concrete to heal cracks in monumental buildings. Introduction This report is prepared to propose to Building Construction Authority (BCA) on the adoption of self-healing concrete to be incorporated into the historical buildings to prolong the longevity of the building structure. This prevents the formation of cracks in monumental and historical buildings. 1.1 Background Information Preserving our heritage through buildings is essential to our future generations. Some of the heritage and cultures were represented in buildings such as the Old Parliament House, which was built in 1827. These buildings were constructed using mainly concrete consisting of Ordinary Portland Cement (OPC), which is known to deteriorate over a long period of time. The deterioration of the concrete in Singapore is mainly due to the shrinkage caused by high temperatures and the acidity of rain. According to Hu, Balasubramanian and Wu(2003), Singapore’s...

Reader Response Draft #3

In the article “Hotel New World Collapse”, Lim (2009) discussed the events leading up to the collapse of Hotel New World, which was caused by a series of engineering faults and poor building management. Hotel New World was a multi-story building that was constructed by Lian Yak Realty in 1971 and was located at Owen Road. According to Lim, the collapse of Hotel New World in 1986 was so devastating that it did not leave any walls and columns standing. After the collapse, rescue teams consisting of both local and foreign specialists were dispatched. Lim stated that former president Wee Kim Wee arranged “a commission of inquiry” to inspect the source of the collapse on 22 March 1986. Lim stated that according to the investigation report, the primary reason for the collapse “was due to inadequate structural design of the building”. The additional installation on the roof also contributed and accelerated the collapse. The investigation report also mentioned that visible “cracks in t...
