Abstract: This paper presents the results of the autogenous shrinkage of ultra high performance fibre reinforced cement composites (UHPFRCC). The stress-strain behaviour of the material under compression, tension and bending was also determined. To design the ultra-compact cementitious matrix (compressive strength of 160 MPa, elastic modulus of 48 GPa, tensile strength of 10 MPa and equivalent elastic post-cracking bending stress of 35 MPa) it was used the concept of maximum granular packing of grains. The particle size of the aggregates ranged from 150 to 600µm. Silica flour, slag-cement, silica fume, wollastonite, steel fibres and superplasticizer were the other constituents of the composite. The water/binder ratio of the mixture was 0.17. The autogenous shrinkage of the UHPFRCC was measured until the age of 90 days when the final deformation reached 856µm/m.
