RECYCLED AGGREGATE CONCRETE: A SUSTAINABLE
2012-7-15 Three recycled aggregate concrete mixes were prepared with 100% RCA obtained from each source. These mixes are designated as MM-RAC, MK-RAC and MV-RAC respectively. In all mixes, the letter M stands for the mix, the second letter represents the source of recycled coarse aggregate and RAC indicate the recycled aggregate concrete.

Recycled aggregate concrete is an eco-friendly material that is increasingly being used in new constructions. Nowadays, this application is mainly limited by user’s lack of confidence, as coarse recycled aggregate (CRA) is usually more porous, i.e., it has a higher water absorption, than coarse natural aggregate.
