Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical uses. It is manufactured by heating sand, soda ash, and limestone to high temperatures to form a molten liquid that is then cooled rapidly. Glass can be recycled endlessly without loss of quality by melting down collected glass containers and bottles. Recycling glass provides environmental benefits like reducing carbon dioxide emissions and conserving energy compared to producing glass from raw materials. Recycled glass has many uses including as fine aggregate in concrete where it can replace up to 10-20% of sand, and in self-compacting concrete which has benefits for construction and architecture.

9. USE OF GLASS WASTE-ARCHITECTURAL USES
• Use of glass wastes as fine aggregate in Concrete:
– While using waste glass as fine aggregate replacement, 28 d strength is found to
marginally increase up to 20% replacement level
– Marginal decrease in strength is observed at 30 to 40% replacement level of waste glass
with fine aggregate.
– Waste glass can effectively be used as fine aggregate replacement.
– The optimum replacement level of waste glass as fine aggregate is 10%.
• Use of recycled glass in self-compacting concrete
– was first developed in Japan
– ability to consolidate by its own weight
• Recycled glass cullet with two particle size ranges (<5 mm and 5–10 mm) were
used to replace river sand and 5–10 mm granite. The fresh properties results showed
that the slump flow and blocking ratio of concrete mixes increased with the increase
of recycled glass cullet contents.
