Objectives And Scope Of The Work

A specific subset of recycled aggregates is recycled concrete aggregates (RCA) where the masonry content is limited to not more than five per cent. The performance characteristics of RCA are better than RA and consequently there are fewer restrictions on the use of RCA in concrete (BS 8500-2)

According to the article, “Energy-Efficient Approach to Cold-Weather Concreting”, Barna, Seman, and Korhonen(2011) introduce a new approach to cold-weather concreting which is antifreeze concrete. They thinks that traditional cold-weather concreting method is expensive and energy in-efficient, because traditional method requires artificial heating of the materials and needs to create a suitable environment for curing normal concrete. This study compare the estimated annual cost in 1991 and in 2011 to show the antifreeze concrete result in saving money and explains an initial laboratory tests to show that “antifreeze concrete mixtures are capable of being workable, entraining air, and meeting the design freezing point.” The authors also explains a performance test to show that the strength gain of concrete cured at -4°C is same as cured at +5°C, and that antifreeze mixtures made concrete be durable. Thus, they conclude that the antifreeze concrete doesn’t need artificial heating which results in saving time, money, and energy in constructing process.

Hathaway Jones is a high-end clothing retailer that despite grossing in $5 Billion dollars in sales in 2006, hardships still threatened the well-being of the company. Fred, who had an extensive background with luxury brands and immaculate credentials, was employed to tackle these issues and revamp the Hathaway Jones image. His aggressive nature made him hit the ground running implementing a cost-saving outsourcing strategy which improved profit margins, merging closer to industry’s standards. Plans to redefine Hathaway’s market towards younger adults, offering trendier affordable clothes was the next task Fred wanted to deploy in efforts of changing the brands image. Since China presented a 70% annual growth rate in luxury goods, it became a highly attractive market for Hathaway’s new image. To access the Chinese market, hefty investments were made to open up a chain of new stores in Beijing, Guangzhou, and Shanghai. With this project almost approaching its debut, Fred was put to the quest to recruit a winning team to handle any and all challenges that may come by and ensure the success of this lucrative market.

Abstract. Considerable network of transportation infrastructures such as highways, rails, and so forth are key providers to economic growth and productivity of countries. Consecutively, Reinforced Concrete (RC) is the predominant construction materials in constructing many of these infrastructures. RC is a unique construction material which allows flexible design layouts and offers safe bending and torsion to satisfy design requirements. However, being exposed to harsh environment and contamination such as salts, acid rain, distilled water, carbonation, sulphur and so on are the reasons for deterioration, thus significantly impacting the performance of these structures. Furthermore, the deterioration of these structures is not only a

Portland cement concrete has been used in the field of construction since the early Roman empire, but until the early twentieth century transporting concrete to great heights or distances was a big challenge. With the invention of the concrete pump handling concrete using wheelbarrows or buckets became obsolete because they require less man-power and can reach those hard-to-get places with ease. There are three types of concrete pumps being used in construction today: truck mounted, trailer mounted or specialized. Each style of concrete pump has it’s advantages and can be tailor made for different construction applications. There is one drawback in using concrete pumps, standard concrete designs can not be used since it is too viscous and would require much larger pumps to reach the required heights. Therefore, admixtures must be added to the concrete design to change the chemical composition of the concrete to make it more flowable. Admixtures are also used to help slow down or speed up setting time, or reduce the amount of water required in the mix depending on the construction site requirements. With such a vast range of applications that concrete pumps can be used for, concrete construction has seen a great increase in production, efficiency, cost-reduction and even safety.

In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of Portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete. Within this process lies the key to a remarkable trait of concrete: it’s plastic and malleable when newly mixed, strong and durable when hardened. These qualities explain why one material, concrete, can build skyscrapers, bridges, sidewalks and superhighways, house and dams. (Cement $ concrete institution) 2015)

Nassar (2007) states the system is the combination of all the processes that are necessary to accomplish the organization 's goals and objectives, which are guided by the organization 's mission (p. 1.8).

The main goals and concerns utilized for this program and policy are the following. “During the preparation phases of the evaluation, scientific, and program staffers must have open communication and consensus around the evaluation goals and objectives, and throughout the evaluation, they must have mechanisms to maintain this open communication.” Which leads to what are the critical ten steps of causation to a successful accomplishment of those finishes. The following ten steps for guiding the outcome evaluations “Clearly define the problem being addressed by the program; specify the outcome the program is planned to accomplish. Specify the research questions we want the evaluation to answer, and select an appropriate evaluation design and carefully consider sample selection, size, and equivalent between the groups. (Pp. 1-9)

According to Tam (2002) concrete is a commonly used construction material in most parts of the world.There are many different types, strengths, and compositions of concrete and all of them have different characteristics that make them perform better for different applications. The following report is an outline of the different aspects of concrete itself. It includes the special concretes and their applications that are best suited for the construction of a shopping mall, the types of extenders that may be used together with the different admixtures.

Continuously reinforced concrete pavements (CRCP) was first designed 100 years ago when the Federal Highway Administration constructed a CRCP testing section. CRCP is now being used in numerous states around the United States and even around the world. CRCP has proven to be such a useful design. With the design and construction growing, there has been many lessons learned through its use and research. Which has contributed to better practices and a longer life cycle, making its ability to maintain a “zero-maintenance” service life through harsh environmental conditions and heavy traffic loadings. As long as proper design and construction is being utilized (as shown in figure 1) the design should need only minimal

It is well recognized that the advanced alteration by built surfaces of natural surfaces, within urbanization, shapes the main due to the formation of the urban heat isolation. Natural surfaces are frequently composed of moisture trapping soils and vegetation. Therefore, they use a large proportion of the radiation that absorbed in the process of the evapotranspiration and emission water vapor that shares in cooling the air in their neighborhood. So, built surfaces are possessed from water-resistant and a high percentage of non-reflective construction materials. As a result, they ensure the absorption of certain proportion of the happening radiation, which is emitted as heat.

Any organization that wants to have a long-term competitiveness and productive outcome in business should consider developing efficient and vibrant managers. Companies like UPS, Pepsi Cola and other CEO’s recognize how critical it is to have a leadership development program to fill the lagging in developing new and current leaders who need the suitable understanding, talents, and capabilities that are necessary to assume positions of leadership. It goes without saying that every organization that wishes to stay on top of their market generate a continuous pipeline of future, and current managers that will be familiar with how to lead effectively in a global and local environment, and carry out the mission of their business. The goals and objectives of the organization must be formulated, implemented and evaluated to manifest its mandate. Our team in accomplishing this task will be using theories, models, and approaches that will help form the purpose and skill set of the future managers including the company itself. Leaders/Administrators that have the competencies to enhance growth and be able to bring about change are greatly in demand. The great Bill Gates once said in an article, “as we look ahead into the next century, leaders will be those who empower others” (Josephson, 2012). As I reflect on the question how does my organization develop and hone leadership skills, performance reviews come to mind? Our organization’s leadership development team will be using a

The behaviour of concrete under a load is an important phenomenon that has to be considered while evaluating and analysing concrete structures. Concrete is one of the most widely used construction materials in the world. So it is essential to understand what concrete is and the properties associated with it. For more than 200 years, this artificial conglomerate stone made up of cement, water and aggregates, has been accepted for its long-lasting and dependable nature. In addition to durability, its superior energy performance, flexibility in design and affordability are some of other important aspects of concrete. (Naik, 2008).

The main purpose of this study is to indicate the performance characteristics and applications of two typical types of specialty concretes: watertight concrete (WC) and self-compacting concrete (SCC). Each of the case study will discuss, first, the mix design procedures and the performance characteristics compared to ordinary concrete; second, the application of each specialty concrete; last, the example of the utilisation of waste materials in each specialty concrete.

The utilisation of supplementary cementitious materials results in several improvements in the concrete composites and reduction in the overall economy and hence they are well accepted. Ground granulated blast-furnace slag (GGBFS) is a by -product obtained from the steel industry which is naturally cementitious and is commonly used as a replacement for cement material in concrete. In this paper our study is mainly confined to a brief study of GGBFS, its production, composition and applications. It further focusses on examination of changes occurring in the properties of OPC concrete such as strength development, setting time, consistency, durability, sustainability, permeability and appearance on partial replacement of cement with different percentages of GGBFS. We conclude that in recent times, GGBFS concrete has served as a major alternative to conventional concrete and has drawn the attention of the concrete industries due to its cement, energy and cost savings, environmental and socio-economic merits.
