Design Specification For Ultra High Strength Concrete ...

Ultra-high strength concrete defined as that having compressive strength from 68 to 124 MPa and a flexural strength of 14 MPa, may be fabricated at a water cement of 0.22. Further, in concrete containing silica fumes, addition of a superplasticizer decreases the water requirement and the pozzolanic action of the highly reactive silica fume also contribute to concrete strength
