ABSTRACT
This study determined performance of different sacrificial anode materials which are aluminum alloy, zinc alloy and alkaline activated zinc alloy to protect corrosion of reinforcing steel in different concrete mix proportions. Water to binder ratio and fly ash content were varied. Moreover, moisture condition of specimen was varied as wet, wet-dry and dry conditions. Initial chloride was mixed during concrete mixing to initiate corrosion of reinforcing steel. Half-cell potential and corrosion current density were measured weekly at anode and steel in different distance from anode. Maximum protective distance from sacrificial anode was concluded based on difference anode materials, concrete mix proportion and moisture condition.
