USES OF GLASS IN CONSTRUCTION Silica is the main constituent of glass. But it is to be added with sodium potassium carbonate to bring down melting point. To make it durable lime or lead oxide is also added. Manganese oxide is added to nullify the adverse effects of unwanted iron present in the impure silica. The raw materials are ground and sieved. They are mixed in specific proportion and melted in furnace. Then glass items are manufactured by blowing, flat drawing, rolling and pressing. Important Properties of Glass: 1. It absorbs, refracts or transmits light. It can be made transparent or translucent. 2. It can take excellent polish. 3. It is an excellent electrical insulator. 4. It is strong and brittle. 5. It can be blown, drawn or pressed. 6. It is not affected by atmosphere. 7. It has excellent resistance to chemicals. 8. It is available in various beautiful colours. 9. With the advancement in technology, it is possible to make glass lighter than c

Abstract The aluminium element was discovered 200 years ago. After an initial period of technological development, aluminium alloys were used in many structural applications, including the civil engineering field. Aluminium is the second most widely specified metal in building after steel, and is used in all sectors from commercial building to domestic dwelling. This paper contains complete overview of use of aluminium in building construction. How it is beneficial in modern age building construction. This paper also contains the properties, advantages. Some question arises that whether aluminium is sustainable, fabricated for fast track, requires maintenance, are explained in detail in this paper. INTRODUCTION 1.1 Why aluminium? Aluminium is the second most widely specified metal in buildings after steel, and is used in all construction sectors, from commercial buildings to domestic dwellings. 40% of the UK annual production of aluminium is utilized within the const
