Aggregate base course (road base) The largest application of recycled concrete aggregate (RCA) is for the aggregate base course in road construction. This term refers to the center layer of the roadbed. A cross-section of pavement would show dirt, or subgrade, as the lowest of three levels, layered on top by aggregate base course, and finally capped on top by pavement, either concrete or

The used aggregates are attaining from the waste concrete plays a huge task in providing the strength to the fresh concrete. For the sustainable growth, Engineers should have to decrease the utilization and exploit of natural resources or materials like sand, aggregates etc or they can use the diverse material for making a structure with the equivalent strength. The alternate method for this

RECYCLED CONCRETE USES. Old, unneeded concrete can be recycled and used to create recycled aggregate. In most cases, recycled aggregate will be used as a subbase material, but it can also be paired with materials and reused as an aggregate in new concrete.

So recycled concrete aggregate is not a hindrance to structural concrete members. Benefits of using recycled concrete instead of natural rock aggregate Save costs- the RCA concrete is much cheaper than the conventional concrete aggregate so that you can lay down a firm base or foundation with less sum of money.

What’s the Process of Recycling Concrete? Recycling concrete is a process of breaking, removing and crushing it from its current location. It is then re-created to be good as new. It is often the best option for concrete removal. Even just a slab of concrete doesn’t make any difference all recycled concrete is aggregated for using subbase

The results are presented in Fig. 1. They show that the recycled concrete aggregates had on average 30% more losses than the natural aggregate. As expected, the strength of the crushed concrete affects the abrasion capability of the aggregate, i.e. stronger concrete results in less loss.

Aggregate test results for several aggregate types including one natural aggregate and two different recycled concrete aggregates have been presented. Three series of mixture proportions were developed which included control mixtures, direct replacement or constant water–cement ratio mixtures, and strength-based mixtures with target compressive strengths of 30 and 50 MPa.
