Jan 5, 2021In terms of compressive strength, UHPC can have up to ten times higher compared with traditional concrete. With regards to resistance to tensile stress, UHPC can have up to 1,700 psi, while the traditional concrete only has 300 to 700 psi. For flexural stress, UHPC can have up to 2000 psi versus 400 to 700 psi of the traditional concrete.
