Abstract

Rapid urbanization has resulted in drastic increase in housing demand today. The traditional or conventional method of construction for mass housing is comparatively, a slow process and has limited quality control, particularly when a large size project is involved. It is therefore obligatory to work out a method or a scheme where the speed and quality of construction are controlled automatically by a systematic approach. Many methods have emerged and have been tried out and are still being adopted ....etc

Aluminium is the most important of all non-ferrous metals. It finds wide applications in packaging, transportation, electrical, machinery and equipment, building construction and consumer durables. Production process involves conversion of Bauxite into Alumina in refinery and which later is converted to Aluminium through electrolysis process in smelter.

The global Aluminium Consumption grew from around 20 MMT in 1994 to about 39.9 MMT in 2010. Consumption is expected to be of the order of 80 MMT in 2020. The demand is primarily driven by str ....etc

formwork and supportive scaffolding ppt

Formwork and scaffolding are extensively used in the construction industry for very specific functions. When construction teams need to mold wet concrete or hold it in place until it hardens to the desired shape, they use formwork. It can be defined as permanent or temporary casings or molds that hold the concrete securely until it hardens enough to support its own weight. Scaffolding differs from formwork significantly; they are temporary structures used as working platforms to support people during con ....etc

1.INTRODUCTION
1.1 What are Aluminum Alloys ?
Aluminum is a revolutionary metal. It changed the scenario in engineering designing for almost everything ranging from utensils to aircrafts. It was also referred to as the gold in its early days of discovery. Aluminum exhibits outstanding strength with low density and light weight. As the engineering marvels developed an increasing demand was witnessed to further reduce the weight of aluminum and to increase its strength for applications like ship building, aircraft de ....etc
