Recycled Aggregate Concrete Quiz

• Every year, millions of tonnes of concrete rubble are generated due to various reasons.
• This rubble can be used for new aggregates in plain concrete or R.C.C. works, with proper corrections in the mix design.
• The recycled aggregates have slightly less specific gravity and more absorption value.
• The strength of recycled aggregate concrete is about 10 to 15 percent less when compared to the concrete with fresh aggregate.
• This can be balanced by choosing a suitable mix design, higher quantity of cement or by using admixtures to reduce the water requirement.

Test your knowledge about the use of recycled aggregates in concrete and R.C.C. works, including their properties and impact on concrete strength. Explore mix design considerations and methods to balance the strength of recycled aggregate concrete.
