Essays on Cement

The intensive growth and more new scientific and technological developments give builders practically unlimited possibilities. But to the fore, the problem of choice comes – how to rationally determine the most appropriate technology? Particularly heated is the debate between supporters and defenders of monolithic construction of prefabricated concrete (bibm.eu, 2016). The main difference of the prefabricated concrete construction from the monolith is manufacturing of building structures in the factory with careful laboratory monitoring of the whole process (concretenetwork.com, 2016). Impact of human factors on the quality of the product is reduced to an absolute minimum, and perhaps it can be ...

Moral Issues

The case for / against the Atlantic Cement Company implicates a set of ethical issues at stake as company's operations continue to inform attitudes of local residents and company owners. The Atlantic Cement Company has a business case for operating a decidedly polluting business (particularly given operation date in 1962). From a business perspective, the Atlantic Cement Company creates jobs for local residents, offers value for local and broader communities (by manufacturing a much on-demand product required for construction works and a host of building- and construction-related industries) and, not least, supports government's efforts to help expand on a ...

Introduction

Currently, coal-fired power plants account for more than 80% of carbon dioxide emissions in the electric power industry of the United States and 33% of all the carbon dioxide emissions in the United States. Consequently, reducing carbon dioxide emissions that come from the coal plants is the focus of most proposals that intend to cut on the greenhouse gas emission. The options to do this include capturing and sequestering carbon dioxide that emitted by the coal power plants, replacing the coal power plants with the low or zero carbon dioxide sources of power like the nuclear and wind energy.

Question 1

Hot-Mix Asphalt Concrete (HMAC) is an energy intensive civil engineering material. According to the Environmental Life-Cycle Assessment studies done on the production of the Hot-Mix Asphalt shows that the process of mixing asphalt and drying of aggregates consumes more energy than the energy required in the extraction of crude oil and bitumen distillation. This aspect is unsustainable since the energy is primarily obtained from fossil fuels (70 to 80% of natural gas is used to produce Asphalt) which are non-renewable energy sources. One way of mediating this shortcoming is to obtain the energy from renewable sources such as solar, ...

Rail construction is a sequence of steps that takes laborious amounts of time in each step and finally results in a wonderful and safe system for transport for many decades to come that requires minimal maintenance over that period. The first step in the construction process is the approval for new line itself. This is typically the responsibility of the government to do it. Once a approval is given for rail connectivity between two points then the role of engineering kicks in. The first step in the process is the alignment. Alignment is nothing but the path in which the track ...

Q.1. The most important argument for a stable schedule is that Lean is not very capable of dealing with a situation where sudden changes in production levels occur, since this affects the other entities in the system. For instance, given a stable process, a sudden change would either lead to stoppage in some part of the assembly, or another such problem. This would lead to a stoppage of work throughout the line. Since the lean system works on a ‘just in time’ concept, suppliers would also be affected since inventory gets shipped from the supplier’s side only when required. Thus, a stable schedule becomes paramount ...
