Feb 01, 2009 The advantages of recycling coarse aggregates from discarded old concrete include lower environmental pollution, reduction in valuable landfill space, and savings in natural aggregate resources. While economy is not currently a major factor in recycling concrete in all regions of the world, however, it may become in the future due to the lower ...

Natural aggregates are products made of sand and crushed stone; and recycling aggregates are made ... Coarse aggregates among 9.54 to 25 mm had absorption of 3.3% in 28 days. Medium aggregates (2.36 to 9.5mm) had 8% and fine aggregates (less than 2.36mm) had 12.7% of water absorption. These differences in porosity are due to the high cement

Coarse aggregate is one of the essential ingredients apart of water and cement in concrete production. It consists about 60 to 75 percent of total concrete production. Coarse aggregate comes from particles greater than 4.75 mm but commonly in a range between 9.5 mm to 37.5 mm. Therefore, the selection of coarse aggregate

The recycled coarse aggregate will invariably have lower specific gravity and higher absorption than the original aggregate, due to the presence of cement paste in the recycled aggregate. The compressive strengths of recycled aggregate concrete are lower than those of the same mix designs made with virgin aggregate.
