Strengthening using CFRP, corrosion and structural monitoring of beams, slabs and pile caps of container decks of a sea-port
Marine concrete structures suffer seawater corrosion, especiall
y under tidal splash zone, which
causes spalling concrete and corroded rebars. The sea-p
ort operator decided to stop further
corrosion and strengthen the corroded structures such as slabs, b
eams and pile caps.
Special formulated CFRP system was used to wrap the structure to stop
further seawater corrosion.
Mini sensors were embedded in the CFRP wrap to monitor corrosion r
ate and evaluate corrosion
levels. Fibre optic sensors were embedded in the CFRP wrap to m
onitor structural behaviours of
the strengthened concrete structures.
