Simple Comparison of Different Concrete Resistance to Sulphate-Induced Corrosion

Abstract

The paper compares the sulphate ion attack resistance in several mixtures of high-performance concrete. The corrosion tests were not performed with the actual concretes, but with model mortars derived from them. The resistance was compared by means of a comparative, specifically double-comparative, methodology. The paper devotes much attention to describing this method, deriving the model mortars, and choosing the correct specimens and parameters to be observed. All important test results, which confirm the effectiveness of the method, are listed. The resistance of each mortar was identified with sufficient accuracy.
