[Audio] Glass is an inorganic product of fusion, which has been cooled to a solid-state condition without crystallizing. slow cooling process leads to formation of crystal nuclei and crystallization takes place. If the cooling rate is fast, leaving no time to the formation of crystal nuclei, structure of super cooled liquid state turns to rigid and forms a glass.

[Audio] Engineering Properties of Glass Transparency Strength Workability Transmittance U value Recycling property.

[Audio] Properties: 1. Transparency of Glass Transparency is the main property of glass which allows the vision of the outside world through it. The transparency of glass can be from both sides or from one side only. In one side transparency, glass behaves like a mirror from the other side. 2. Strength -The strength of glass depends on the modulus of rupture value of glass. In general glass is a brittle material but by adding admixtures and laminates we can make it as more strong..

[Audio] A glass can be molded into any shape, or it can be blown during melting. So, workability of glass is a superior property. 4. Transmittance The visible fraction of light that passing through glass is the property of visible transmittance. 5. U value of Glass U value represents the amount of heat transferred through glass. If a glass is said to be insulated unit then it should have lower u value. 6. Recycle Property of Glass Any glass can be 100% recyclable. It can also be used as raw material in construction industry..

[Audio] Types of glass: Float glass Shatterproof glass Laminated glass Extra clean glass Chromatic glass Tinted glass Toughened glass Glass blocks Glass wool Insulated glazed units.

[Audio] Advantages Easily moulded Glass is basically a translucent material, created by the application of heat to sand. It can easily be moulded into any shape which makes it one of the most versatile materials to be used in the construction of buildings and also, one of the most frequent ones. Visible transmittance Using glass in architecture not only allows you to get visually connected to the outer world, but it also allows natural light to flow in even if the house is closed. Weather and rust resistance Unlike any other material, glass can withstand the effects of water, wind, sun and other environmental effects, without losing an inch of its appearance and integrity. Excellent insulator against electricity Glass is considered to be an excellent insulator. In the absence of free electrons, it ensures that you are safe from any possible electric hazards. Recyclable A glass is 100 percent recyclable i.e. it does not degrade during the recycling process and can even be used as a raw material in the construction industry. Adds to the beauty of the structure Using glass as a building material accentuates the beauty and elegance of the building. It has a smooth and a glossy surface, which makes it an ideal material for showrooms and showcases.

[Audio] Disadvantages Easily breakable Glass, when subjected to the slightest of stress, breaks without strain. Further, the broken edges of glass are sharp enough to cause injury. Unsafe for earthquake proven areas Buildings in the earthquake proven areas need to be specially designed in order to take the additional stress. However, glass, being brittle in nature, tends to collapse easily. Heat absorbent Glass generates a high level of solar radiation and traps heat which eventually warms up the interiors. Therefore, it might not be suitable for the construction of buildings, typically existent in the hot regions. Increase in the cost of security Using glass in a building enhances the cost of security because of the transparency that it offers. Increase in the overall cost of the building Glass, being an expensive material as compared to the other materials used in the construction industry, eventually augments the total cost of the building. Glass is one such material that is colossally being used in modern architecture nowadays. The versatility of the material has increased by leaps and bounds, and it is now being used as an insulation material, structural component, external glazing material, and cladding material etc. in the construction of buildings, worldwide. Despite being on the costlier side in comparison to the other building materials, the intensifying popularity of glass in building construction cannot be denied.
