Résumé : An experimental study on mortars made from crushed limestone aggregates, where Portland cement is replaced with limestone fines, slag, and natural pozzolana, reveals that the mechanical properties of these mortars is affected by the concurrent inclusion of these three additives in their cement matrix. The additives are proportioned in the cement as follows: limestone fines at 30%, slag at 10%, and natural pozzolana at 10%, compared to a control binder without any mineral additions. For continuous immersion tests, the sulfuric acid solution is maintained at a 5% concentration. Limewater is used as the reference medium. It has been demonstrated that mortars containing these quaternary binders, when immersed in sulfuric acid, exhibit superior compressive strength compared to the control mortar.
