Abstract
Ultra-high performance concrete (UHPC) is prized for its superior strength and durability. These qualities have made it an emerging choice for bridge construction and repair, but high material cost has historically made it cost-prohibitive for many practical applications. Following extensive investigations, researchers at Iowa State University developed a more affordable nonproprietary UHPC mixture using readily available materials. Tests indicate that the mixture’s strength and durability are comparable to proprietary mixtures at one-third of the cost, offering a promising alternative for Iowa bridge structures.
