Material used in engine block casting Essay Sample Material used in engine block casting In order to meet the above functional requirements the material used for manufacturing the product should contain many properties. They are, the material should contain high strength, modulus of elasticity, wear resistance, ability to withstand vibrations, and corrosion resistance. High strength is mostly concerned in diesel engines because of their high compression ratios compared with petrol engines.

Hire Writer At present, over chemicals formulas are used in the glass manufacturing industry Lee, Jr. During the twentieth century, the modern era of glass brought forth magnificent skyscrapers redefining the skyline. In addition, glass cladding of buildings fulfils functional requirements of lighting, heat retention and energy saving.

Not all glass components used in the construction industry are structurally loaded, and they can be found in non-structural lightweight concrete, paints, partitions and waste water filtration devices just to name a few.

Glass can be found in both translucent and transparent forms, and is perceived as being superior and more economical and sustainable than that of cement, concrete and steel.

Recycling Basics

One such structure is the glass beam which had limited span length but can be joined to lengthen its span to at least times the original. For example, the Yuraku-cho station in Tokyo has a Figure 1 Yuraku-cho underground station in Tokyo, Japan source: These columns made from glass create an interesting visual feature that is appealing to the eyes and give the appearance of an uninterrupted open space.

Although glass is strong in compression, there is still a fear of brittle failure, hence the overdesign of the structures being supported. In addition, load distribution of the applied load must be carefully uniformly distributed to prevent the development of concentrated stress that can trigger a brittle failure.

Figure 2 Columns of glass in Russia Source: They enhance the appearance of a building and allow a connection to the adjacent environment whether from a top floor of a skyscraper enjoying the scenery or from a few millimetres away from sea-life in an aquarium or zoo. Therefore, these transparent glass walls serve as a connection to the outside environment and they also protect us from elements and dangers outside of the building envelope.

Design considerations must be given to the thickness of these walls and load transfer, and must also be comprised of multiple layers to minimise the risk of concentrated stresses which can cause a collapse from a fracture.

Safety standards must be adhered to at all cost to ensure the walls protect the occupants for a period of time even after a failure. Figure 3 Glass walls structural members and partitions Source: Regardless of its intended use, several benefits and drawbacks will have to be considered such as, light penetration and thermal properties, in addition to the structural specifications that must be followed.

If ignored, the occupants of these structures can experience undesirable discomfort due to intense thermal gain. On the other hand, this can be regulated with the use of modern polyvinyl butyral PVB technology and glass tint, to reduce the thermal gain and create favourable conditions.

These are mostly in use as pedestrian foot bridges, as designers try to prevent surface scratches which can increase the potential for failure due to increase tensile forces. This study will look at the following: The literature will then be used to identify suitable applications and make recommendations for the use of recycled glass in the construction industry.

The lack of information and practical application within the region is limited and therefore do not produce a good representation of the Caribbean.

The glass has the following physical properties Lee, Jr.

On the hand, the specific gravity of glass cullet is significantly lower than that of crushed rock and will affect the relative density and compaction unit weight of cullet Table 1. The comparison between performance and compaction density will be seen as a negative attribute. In contrast, Mayer, Egosi and Andela asserted that when glass is used in concrete, it provides an abrasion resistance that only a few natural stone aggregates and expensive special floor toppings can achieve.

Evidence of this can be found in 6 Page many glass products constructed around the world. One such location is the Itabashi City in Tokyo, Japan, which took the global recycling movement by storm, and engaged in the glass recycling programme with great success Japan Local Government Centre The city utilized the tiny pieces of crushed waste glass less than 1mm to practical use as raw material for architecture, paints and coatings, where the distinctive colours are still visible in the final product.

Some of these effects can be seen in the pavements, wall coatings and bollards, to name a few Japan Local Government Centre Other architectural and decorative applications such as precast wall panels, park benches, planters, floor tiles and trash receptacles are potential products of recycled waste glass Mayer, Egosi and Andela The application of glass cullet as a substitute for conventional aggregates can be handled spread and compacted with traditional construction equipment in backfills, roadway base course, sub-base or embankments and utility trench beddings Lee, Jr.

Various laboratory compaction tests can be used but this is guided by the compaction method to be used in the field. One of these tests is the modified Proctor compaction method.

This test was used in Lee, Jr.

Sand or washed gravel are the more traditional granular materials used in drainage applications with ranges from 0. The ranges above are in contrast with Table 1 compaction data, which illustrates a range from 0. Other uses of cullet are filtration medium in swimming pools, septic fields and water purification applications.

However, Nebraska State Recycling Association indicated that a further study of the filtration capacity is needed. Traditional methods used are by means of geotextiles but glass cullet also has its place in this application. Cullet can also be used as a composite material with thick non-woven geo-textiles to offer a drainage solution preventing the movement of soil particles from water flow.How to organize material for your essay.
