    abstract = {As Construction and Demolition (C&D) waste
create environmental pollution, many studies have been
conducted to seek the potential uses of the construction
and demolition waste in particular, concrete waste. A
visible solution to such problem is to recycle the concrete
waste as aggregate to replace the natural aggregate in
various applications. Furthermore, the use of RCA can
potentially reduce the dependence of the concrete industry
on natural aggregates, maintain the natural aggregate
resources, reduce the amount of C&D waste that is
disposed in landfills and consequently ensure C&D
sustainability for the benefit of the industry and the
national economy. However, the use of the RCA as a
substitute for the natural aggregate in concrete
applications is not conventional because of the differences
between the properties of RCA and the natural aggregate
which limited the utilization of RCA mostly to 20-30% of
the total natural aggregate. Moving towards the fully
utilization of the RCA in the concrete industry could lead
to a situation much closer to that of sustainable
development. This study provides introduction on current
status of production of recycled concrete aggregate,
reviews and analyses some of the most substantial
research findings over the past few years regarding the
material aspects. It also attempts to elucidate the
approaches for the better performances, identifies the gaps
in the existing knowledge and underlines the reasons why
this promising technology has not become widely
accepted by the industry.}
