The crushed returned concrete aggregate has useful aggregate properties because it is free of any contamination. Thus, CCA is distinguished from other recycled concrete aggregates that come out of existing structures with possibly high contamination from many years exposure during the structures' service lives. CCA has potential as an internal curing agent due to its high absorption capacity ...

Both gravel and crushed stone are generally acceptable for making quality concrete (Photo 9), although gravel is usually preferred for exposed aggregate. The use of recycled concrete, crushed to propersize concrete aggregate, has also demonstrated successful performance. Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good ...
