Most recently, Emmanuel Denarié is the one at the origin of the development of next generation ultra high-performance fiber-reinforced concretes (UHPFRC) with synthetic UHWM PE fibers, adapted for structural applications (project within SNSF NRP 70 and supervision doctoral thesis Amir Hajiesmaeili - 2019). These new materials dramatically decrease CO2 emissions and Embodied Energy footprints and open a wide field of new opportunities for the rehabilitation of existing structures and construction of new ones.

Note that extreme care has to be taken to avoid the dissemination of synthetic "plastic" fibers in the environment. Norway banned in 2015 discontinuous polymer fibers used in FRC, in road tunnels, see:

Courses

Statics (for GC)

The aim of this course is to develop an understanding of static models of structures. It presents the study of the interplay of forces in isostatic constructions made up of bars, beams and cables.

Engineering of existing structures

The engineering of existing structures encompasses the examination of condition and load-carrying capacity, decision criteria, and methods for rehabilitation or strengthening. This course presents the bases necessary for this approach at the level of materials and structural response.

Materials and structures

Starting with basic knowledge of concrete technology, this course provides an understanding of the relationships between the composition, processing, microstructure and structural properties of "new concretes", with a particular focus on Ultra High Performance Fiber Concretes (UHPFRC).
