Title: Influence of the Composition of Concrete on the Corrosion Protection of the Reinforcement
Author(s): P. Schiessl

Abstract:Report presents a discussion on the influence of the concrete composition on the pore structure and the binding capacity of the matrix and the corresponding effects on carbonation, diffusion of chlorides, depassivation of the reinforcement, and corrosion rate. The most important parameters are the water-cement ratio; cement type; blending agents; cement content; and additives and admixtures. The concrete composition must be adapted to the environmental conditions (micro-climate at the concrete surface). Sufficient quality of concrete cover can only be achieved by a sufficiently long moist curing. The interrelations with respect to the influence of the concrete composition on the various durability aspects are very complex and need further detailed investigation.
