This paper presents an experimental analysis of recycled concrete (RC) in which the natural aggregates are replaced by recycled concrete aggregates (RCA). This experimental program covers the specifications of the
aggregates employed, together with that of the concrete that is manufactured
The considerable effect on the permeability of RC that is produced by the use
of RCA is described and discussed. Tests reveal considerable increase in
permeability of RC in comparison with the reference concrete. Both the water
penetration depths and the permeability coefficients are increased in a manner
that may be correlated with the increase in the replacement of natural aggregates
by RCA. These increments are attributed to the high porosity of RCA.
