Precast Concrete Piles – Advantages & Disadvantages

Precast concrete piles are cast, cured and stored in a yard before they are installed in the field mostly by driving.

Advantages of Precast Concrete Piles

1. Reinforcement used in the pile is not liable to change its place or get disturbed

1. The defects in pile can be easily identified after the removal of forms, and these defects (such as presence of cavity or hole) can be repaired before driving the pile.

1. The cost of manufacturing will be less, as a large number of piles are manufactured at a time.

1. Precast concrete piles can be driven under water. If the subsoil water contains more sulphates, the concrete of cast in situ piles would not set. Thus precast concrete piles have added advantage in such a circumstance.

1. Precast concrete piles are highly resistant to biological and chemical actions of the sub soil.

1. Better quality control can be implemented as compared to bored cast in situ piles.

1. These piles can be constructed in various cross-sectional shapes such as circular, octagonal or square.

GASIFICATION – THE ULTIMATE SOLUTION TO THE WORLD’S ENERGY NEEDS AND ENVIRONMENTAL PROBLEMS

The combustion of fossil fuels is taking a tremendous toll on the earth’s atmosphere and consequently on the environment. Global warming and pollution threaten the very existence of life on our planet. Moreover, most fossil fuel resources are expected to become depleted within the next few decades and thus prices have already skyrocketed. Governments, scientists and even industrialists themselves have long realized that fossil fuels will not remain economically and environmentally feasible and are thus looking towards alternative sources of energy such as nuclear, solar, wind energy and so on. One of the most practical and efficient methods of energy production is gasification – a process which involves conversion of organic or carbonaceous materials into hydrogen, carbon dioxide and carbon mono oxide.

There are 7 billion people on this earth and they produce tones of organic waste every day. This waste is can be used to solve the energy needs of the world. When organic material decomposes in nature, it releases greenhouse gases into the air and the remnants serve to nourish the soil. The process of gasification is similar to what happens in nature, except for the fact that it takes place much faster. Organic waste is used to create gases which are burned to produce energy and the remaining ash is used as a fertilizer. Even when the gases are derived from fossil-based carbonaceous substances, the resulting gases are much more efficient than the original fuel as they can be burned at higher temperatures and even in fuel cells.

INTRODUCTION OF CIVIL ENGINEERING

There are many people who would like to work in the engineering field as the civil engineer in recent years. What would the civil engineer do? You would find some ideas here.

In the past, the field of civil engineering covered many areas. For example, there would be coverage over the use of chemicals in the field. There would also be more details about the mechanical sides. But you would probably find that things have changed in recent decades. More and more specific fields are separated from the civil engineering field. They became the chemical engineering and other specific fields. The traditional civil engineer therefore now covers fields like design and building constructions. There would be, in other words, a narrower definition of the work that the present civil engineers would do.

Softwares For Civil Engineers

AutoCAD:-  

AutoCAD is a semi parametric software tool that is used for drafting and 2D Design mostly. This software is invented by Autodesk Inc. in earlier 1982, now they published AutoCad 2015 their 29th version that is AutoCAD 2015. This is used for making layouts of the residential or commercial buildings. It is world famous software and used by all industries.

Staad Pro :- 

STADD PRO v8i is purchased by Bentley in 2005, today in market they launched Staad Pro v8i Select Series 5. It a geometry based Analysis Software, all industries used this at higher end. All Types of buildings are analyse with different kinds of loads acting on it suck as Seismic Load, Wind Load, Vehicle Load in Bridges. This software contains 70 Countries Codes from worldwide, and 30 Indian Codes Suck as IS456, IS 800, IS 1893 etc. 

 Google SketchUp:-

Google SketchUP is the best ever software for work in 3D drawings and Rendering. One of the main from its feature is that its licence is at very low cost and easily google sketchup available. For interior and exterior design of buildings this software is compatible in all directions. Mostly this software is used for walkthrough purpose. It means we can see the virtual images of our building before construct It is also called Rendering. This Software has a one more feature that is Geo Location Access, it means we can upload our building in google earth in any area, it can show the real environment of the surrounding where you placed the building.
