ENG C292 Concrete Engineering & Durability of Concrete( Curriculum BACHELOR OF ENGINEERING IN CIVIL) - Essay Example (www.cowi.com, 20-). Since the concrete is fundamentally a man-made material, it is quite possible to control its characteristics and behavior by altering its mix design specifications and adding admixtures to it. Hence, by the careful selection of appropriate materials for preparing the concrete, and close monitoring of its curing once it has been cast, the qualities of concrete can be significantly enhanced to meet the requirements of a particular structure. There are certain design requirements associated with every location and type of a structure. If the structure is made of concrete, the concrete needs to be customized in order to combat the challenges brought to the structure by the weather conditions and temperature of a particular location. This needs an appropriate evaluation of the required properties of concrete by studying the literature for the history of challenges associated with a particular climate. Also, the achievement of required results requires monitoring the w hole process right from the start that involves concrete making, casting and finally the curing. Of these, the last two processes are majorly field-specific and require careful supervision from the workers in the construction site. The first part i.e. preparation of the mix design is the most influential process in achieving the desired durability in the concrete. This paper discusses the common methodologies used for the achievement of durability in concrete structures. Concrete has long been in use as a construction material for a large variety of structures including bridges. A number of long-lived concrete bridges have been constructed in the past. They include the Shakh Isa bin Salam Bridge in Bahrain and the bridge over the Lerez River at Pontevedra in Spain shown in the figure-1 and figure-2 below: In his report, (Paeglitis, n.d.: 1) has mentioned that more

Business ethics - Article Example I agree with the author’s statement that a conjunction of motive, means and opportunity creates an ethical hazard (Pendse, 2012). This approach is complimented by the definition of fitness hazard as a tendency of an entity to take undue menace whose costs are not borne on them (William, 2007). I deem author is aiming at providing rules and procedure that will help curb ethical hazards. This is seen in the light of providing an ethical hazard marshal to minimize these tribulations (Pendse, 2012). An instance is given of the leading company, Enron. The management styles and executive decisions of the executives of the company led to an enormous financial crisis.(William, 2007). Therefore, the executives were convicted and received extensive penitentiary terms. Although I liked the way the writer proposed the initiative of teaching ethics in business schools to curb future occurrences, I think the proposal would be essential in schools of all disciplines and not only business school(Pendse, 2012). This is because, ethical deeds are a must for the growth of any being in their job place, in households, and in their day to day actions. In my view, I think the author is wrong in assuming that other past scandals were restricted in the corporations they occurred in since for every ethical hazard that happen other institutions and individuals suffer with it(Pendse, 2012). The difference is in the magnitude, for example, in the article the scandal at Enron destroyed, not just the company, but the rest of the world, as well (Conrad, 2010). This does not inevitably mean that other scandals that seem restrictive do not spread their downfall. In stating that the fiscal crisis at Enron was totally â€Å"unforeseeable and unpredictable†, I feel that the author is contradicting himself. This is seen in the subsequent line where he states that Warren Buffet had previously warned of the looming danger. The danger was, as a result of the the increasing leverage and
