Abstract
The behavior of axially loaded columns constructed from recycled coarse
aggregates (RCA) was studied. Two different concrete mixes with varying ratios of
RCA (0, 20, 40 and 60%) are conducted to achieve a compressive strength of 35 MPa.
The test variables include the two different mixtures and replacement ratio of RCA.
The results of specimens with RCA not more than 40%, showed that the structural
performance of specimens using superplasticizer was similar to that of natural
aggregate concrete specimens. The specimens were analyzed using the finite element program ABAQUS (version 6.14). The models show acceptable correlation and are
used to conduct a thorough parametric study on various design configurations. It is
found that increasing the ratio of RCA plays a significant role in decreasing the
columns ultimate capacities especially when the ratio exceeds 40%. .
