Ultra High Performance Concrete

Utilizing UHPC in Faรงade Design


Ultra High Performance Concrete Characteristics Compressive Strength 25,000 to 30,000 psi Flexural Strength up to 6,000 psi Direct Tension up to 1,450 psi Ductility Greater capacity to deform and support flexural and tensile loads, even after initial cracking. Abrasion Resistance Similar to natural rock Impermeability Almost no carbonation or penetration of chlorides.
