Abstract (Bold 12)
The corrosion behaviour of rainfall exposed steel bar in 1M acid, 1M alkaline and 1M salt solutions has been studied. The exposed and unexposed coupons were immersed in the media for thirty days, at 25oC–32oC. Using weight loss method, the acid corrosion of exposed and unexposed bars in 1M HCl was 0.55 to 0.27 MPY and 0.71 to 0.38 MPY respectively. The alkaline corrosion was same (7.8×10-4 to 1.29 ×10-4 MPY) in NaOH solution. The corrosion rate of both bars in 1M NaCl solution was respectively 4.65 ×10-3 to 3.88 ×10-3 MPY and 3.1 ×10-3 to 3.23 ×10-3 MPY. (TNR, 11)
