The report presents concretes properties at high temperature of a High Performance concrete (HPC) M100. These properties have been studied extensively in the frame of the National French Project HPC 2000. The report provides the composition of the concrete and its constituents, mass transport properties (porosity, permeability...), thermal properties, mechanical properties (strength, thermal strain, transient thermal strain, fracture energy...). In addition, the report includes the results from pore pressure and mass loss measurements (PTM) at high temperature. Finally, several tests have been carried out on fire exposed large-scale specimens, beams, columns and walls.
