Research: Recycled Concrete Aggregates
Even though Recycled Concrete Aggregates (RCA) can readily pass the prescriptive requirements
for coarse aggregates in structural concrete (ASTM C33 2008), the variability in material
properties and quality needs to be quantified and incorporated into design. As a result,
no engineering guidelines/standards currently exist for the design and construction
of reinforced concrete utilizing RCA. Little or no previous work exists on the service
and ultimate load performance of prestressed and non-prestressed concrete structures
utilizing RCA from U.S. sources. Likewise, little or no previous work exists to quantify
the economic and environmental benefits of using RCA in structural applications. The
following list contains the presentations Dr. McGinnis and his research partners at
UT Tyler, New Mexico State University, and Notre Dame have given to highlight the
results of their research into using RCA for improved sustainability of reinforced
concrete building structures:
