Abstract
This paper evaluates the use of cedar tree exudate in chloride penetration and the probability of steel corrosion in reinforced concrete (rc), considering 0.3, 0.5, 0.7, and 0.9 % exudate by cement weight in the mixture at water/cement (w/c) ratios of 0.55 and 0.60. Under these conditions, cylindrical specimens of 4 inches in diameter and 8 inches in height were constructed. The water-sol- uble chloride content of the extracted concrete powder was measured at 0.5, 1.0, and 2.0 cm depth according to astm C1218/C1218M, while the probability of corrosion was determined by measuring electric potentials with astm C876. A favorable incidence of 0.46 % by weight of concrete was found when using 0.7 % exudate at the w/c ratio of 0.55 at the closest depth to the steel, compared to the 0.55 % target. The probability of steel corrosion is reduced to 10 % with potentials higher than -0.2 V with more prolonged exposure to chlorides.
