Recycling concrete from demolished structures can help reduce construction waste and extend the life of landfills. Concrete can be reused in places like landfills, retaining walls, foundations, and road pavements depending on its shape and condition. The advantages of recycled concrete include lower transportation costs since it can often be recycled near the demolition site and reduced carbon dioxide in the atmosphere from crushing. However, recycled concrete may experience downgraded quality with increased water absorption and reduced compressiveness.

2. Recycling is the process of use the waste material for
our requirements in a useful manner.
In this we are dealing with the an innovative study of
recycling of concrete from demolished structures.
concrete can be reused and recycled many ways but
it all depends on how that piece of concrete is and what
the shape of concrete and where it can be useful.

3. WHERE IT IS USEFUL
• Landfills
• Good appearance purpose
• For the use of compound walls in forms
• Existing road pavements
• In retaining walls and abutments
• Foundation

4. ADVANTAGES OF REUSED
CONCRETE
• Reduce the construction waste and extending the life of
landfills.
• Reduces the transportation costs because concrete can often
be recycled in areas near the demolition site
• While being crushed into pieces large amount of carbon
dioxide is absorbed. The amount of carbon dioxide in
atmosphere will be reduced.
• Reduces the need for new landfills

5. DISADVANTAGES OF REUSED
CONCRETE
• Downgrading of quality of concrete.
• Increase in water absorption capacity ranging from 3% to 9%.
• Reduces the workability of concrete.
• Decrease in compressive strength of concrete (10-30%).
