Résumé

 

L’activité pouzzolanique est le processus chimique qui génère, au cours de l’hydratation du ciment, la naissance des nouveaux silicates de calcium hydratés (CSH). Ce travail vise à activer thermiquement une argile pour fabriquer une pouzzolane artificielle qui mélangée avec le clinker permettra d’obtenir un ciment conforme aux normes. L’optimisation du cycle de traitement thermique est obtenue en faisant varier les températures, les temps de maintien, et à travers les changements structuraux par DSC, ATG, IRTF de suivre l’évolution des résistances mécaniques. On montre que la pouzzolanicité optimale est obtenue si l’argile est calcinée à 700°C pendant 5 heures.

Past ten years, literature is an increasing number of works trying to identify the different levers to operate to encourage innovation within companies. In continuation of this work focused on the emergence of a "culture of innovation," the state of the art made ​​in this article allows us to bring about a feeling of "psychological safety" is the only means that:
- Members of the organization are not paralyzed by fear of failure and continue to offer bold initiatives,
- These players learn from the mistakes that will inevitably be committed during the innovation process and are able to no longer reproduce. We suggest, as such, some lines of thought to create a culture of "room for error" in organizations, starting with the consolidation of the reward and sanction systems by the inclination of the direction to "Legends" failures. We stress however that this may be possible in the context of American culture is not necessarily in that of French culture.
