ABSTRACT
Recent developments in the constitutive modeling of geomaterials are based on a micro-mechanical description of the physical and chemical interactions involved at the scale of their microstructure. The main constitutive models resulting from this micro-mechanical description are presented in this article. Such models can be either analytical (named "micro-mechanical constitutive relations"), or numerical (built using the discrete element method). Some micro-mechanical elements may also be introduced in more classical phenomenological visco-elasto-plastic relations.

INTRODUCTION
This second part of the techniques for using hydraulic concrete lists the essential points to be addressed in the choice, design and use of formwork, on the one hand, and the precautions to be taken to ensure good durability of the reinforcement used in the reinforced concrete material, on the other.
