SubjectCorrosion (of reinforced concrete)
AbstractIn this paper, experimental investigations on the corrosion of reinforcing steel bars embedded in slabs containing high volume fly ash (HVFA) concrete were undertaken. The corrosion resistance of the rebars in slabs was then compared to a control mix of conventional Portland concrete (PC) having the same w/ em ratio. Reinforcing steel bars were embedded in these slabs with different depths of concrete cover in order to investigate steel corrosion induced by chlorides. The chloride profile was assessed using acid soluble chloride analysis technique to examine the effect of HVFA in reducing the ingress of chlorides into concrete. Tests of reinforcing steel bars embedded in PC with higher water/ cement ratios (w/ c :::: 0.43 and 0.55) were also included for comparison purpose.
