Abstract

The corrosion resistance of commercial aluminium (95% pure) in simulated concrete pore solution (SCPS) prepared in natural sea water
has been evaluated in the absenceand presence of curcumin extract and Zn2+.It is observed that Aluminium is more corrosion resistance in
SCPS than in sea water. When curcumin extract is added to SCPS, the corrosion resistance of Al increases. However, in the presence of
curcumin –Zn2+ system, the corrosion resistance of Al in SCPS decreases.

Key words: concrete corrosion, aluminium, simulated concrete pore solution, curcumin, green inhibitor.
