Performance enhancement of recycled concrete aggregate

2016-1-20  Katz (2004) adopted ultrasonic water cleaning repetitively to remove the weak adhered mortar until the water was clear. They found that it was effective in removing the adhered mortar, and increased the compressive strength of the recycled aggregate concrete; but the strength increase was about 7% at 28 days.

Performance enhancement of recycled concrete aggregate

2016-1-20  Recycled concrete aggregate due to its residual adhered mortar has low specific gravity and high water absorption. Both of these impediments contribute in the increase of permeability and shrinkage, decrease in compressive strength and hence concrete quality produced from recycled concrete aggregate.

2021-7-22  Aggregate is an essential component in concrete, occupying 60–70% of the concrete by volume. Nevertheless, the application of natural aggregate (NA) is restricted due to the finite resources and long regeneration period. Recycled concrete aggregate (RCA), as common CD waste, has received widespread attention for its usage to replace NA.
