Glass is a hard substance which may be transparent or translucent and brittle in nature. It is manufactured by fusion process. In this process sand is fused with lime , soda and some other admixtures and then cooled rapidly. Glass is used in construction purpose and architectural purpose in engineering.
Engineering Properties of Glass
Transparency is the main property of glass which allows the vision of 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 mirror from the other side.
Strength of glass depends on 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.
A glass can be molded into any shape or it can be blown during melting. So , workability of glass is superior property of glass.
The visible fraction of light that passing through glass is the property of visible transmittance.
• U value
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.
• Recycle property
Any glass can be 100% recyclable. It can also be used as raw material in construction industry.
