decreased the effect of rubber aggregate on the chloride-ion permeability of
concrete.
The same authors (Gesoglu and Guneyisi
2011
) reported the effect of FA on the
chloride-ion permeability behaviour of self-compacting concrete with rubber
aggregates. There was a progressive increase in the chloride-ion penetration as the
rubber content rose. Extending the curing period from 28 to 90 days slightly
improved the chloride-ion penetration behaviour. Incorporating FA slightly
improved the chloride-ion permeability behaviour of the rubberized concretes at
28 days. However, when the curing period was prolonged to 90 days, incorpo-
rating the FA into the self-compacting rubberized concrete mixes significantly
enhanced the resistance of the mixes against chloride-ion ingress. This finding was
attributed to the long-term reaction of FA, which refined the pore structure of
concrete and reduced the ingress of chloride ions.
