Ultra-High Performance Cementitious Composites (UHPC) are a class of ultra-high-performance cement-based composite materials designed based on the theory of closest packing. UHPC is a specific type of Fibre Reinforced Cementitious Composites (FRCC).
1 : High Compressive Strength: The compressive strength of ordinary concrete is 30 to 50 MPa. The compressive strength of UHPC is 120 to 240 MPa.
2 : High Tensile Strength: The tensile strength of traditional concrete ranges from 2.5 to 5 MPa, whereas that of UHPC is approximately 10 MPa.
3 : Durability: Concrete prisms were immersed in a water bath to test their resistance to freeze-thaw cycles; after 600 freeze-thaw cycles, the UHPC retained 100% of its material properties.
4 : Chloride Permeability: When tested, UHPC exhibits an extremely low chloride migration rate—less than 10% of that of ordinary concrete.
5 : Abrasion Resistance: UHPC possesses excellent abrasion resistance, which is nearly double that of ordinary concrete.
