Ultra-High-Performance Concrete - an overview ...

Ultra-high-performance-concrete (UHPC) is generally defined as concrete with a compressive strength greater than 150 MPa. UHPC typically is made with high-strength steel fibers, fine sand, cement, fly ash, a large volume of SF, and a low amount of water (a w/cm ratio less than 0.20). Graybeal (2006) has found that the chloride permeability as ...

High Performance Concrete - an overview ScienceDirect

2021-8-3  Despite the higher material cost, the use of high-performance concrete is found to be economical for columns of tall buildings, as the amount of steel reinforcement can be reduced. In bridges, the reduction in deck size and weight effectively increases the allowable unsupported span. For a continuous bridge, the number of piers can be reduced.
