This study presents the experimental results on properties of concrete
with replacement of natural aggregate by recycled concrete aggregate (RCA).
Experimental data on the creep behavior of concrete mixtures (basic and drying
creep) was obtained. The replacement factor of natural aggregate by RCA were
0%, 15%, 30%, 60% and 100%, and the test conditions were 50% RH and 20°C.
The results of these trials were used to provide a comparison with results of tests
on the reference concrete, for ages up to 270 days. The creep coefficient data
(instantaneous, basic and drying) presented, along with the maximum strain and
the specific creep data. The results reveal considerable increase in creep when is
increase replacement of natural aggregate with recycled concrete aggregate. The
drying creep, especially shower more significant increase when compared to the
