The first article  dealt with the fine-scale petrographic characterization of a set of aggregates rep-resentative of the diversity of Europe’s quarries. The levels of rock alteration were estimated in thisfashion. The mobilization of alkalis in alteration products serves to limit the reactivity of aggregateswithin a basic medium, from which the alkali-reaction originates . This second article appliessuch a concept to reactivity in an acid medium.Ion exchanges between the filler, the most highly-reactive part , were studied in an aqueousmedium and the ensuing water analyses could be compared with water extractions performeddirectly on cold-rolled mixes, in order to evaluate the pertinence of these exchanges.
