Recycling old concrete serves to reuse concrete waste as aggregate in concrete. Recycled aggregate has lower compressive strength, impact strength, specific gravity, and absorption value compared to fresh aggregate.

Millions of tons of waste concrete are generated worldwide every year for the following reasons:
Benefits of Recycling Concrete: The damaged concrete is usually disposed of in landfills, but due to greater environmental awareness, it is recycled for reuse in concrete works. There are several advantages to recycling concrete over throwing it away or burying it in a landfill. Maintenance of concrete waste from landfills saves space there.
Other advantages of recycled concrete are:
Using recycled materials as gravel reduces the need for gravel extraction. There are also economic benefits. Recycled concrete is a building material that municipalities don’t have to pay for those who make waste concrete pay a fee to recycle it.
The strength of recycled concrete is about 10 to 15 percent lower than that of fresh aggregated concrete. However, suitable mixing projects can be carried out and reliable results can be obtained.
