Abstract: 
The objective of this work is the study of the valorization of an addition mortar which is extracted from a natural pozzolan deposit in Bouhamidi located in the region of Beni Safi.We chose to study this natural addition because of its low cost and its pozzolanic reactivity. Thus, we performed several experiments focusing on the influence of the addition amount, as well as the fineness on the corrosion of reinforcement in mortars. We have measured the corrosion potential and the mass variation of different mortars based on pozzolan content (10%, 20% and 30%). The results indicated that is it possible to highlight the beneficial effect of this addition. The analysis of achievements shows that the addition of the pozzolan in optimal quantities has the following advantages:
- Protection of reinforcement against corrosion
- Increase of the resistance against sulfate attack
- Gain in mass of pozzolan mortars in the sulphatic environment.
