ABSTRACT: The effect of added carbon black to concrete mix on corrosion of steel reinforcement was studied.
This was achieved by inserting steel bars in different concrete mixes containing 0.1, 0.2, 0.3, 0.4,
and 0.5, carbon black/cement. Samples were cured, immersed in 3.5% chloride solution for 6
months. Chloride permeability and corrosion rates were measured. Tests showed that corrosion
rate and chloride ions penetration decreased with increased carbon black content. This was expressed
due to filling effect of very fine particles of carbon black and was in the order less than
250 nm.
