Developing UHPC

Durability Properties of a Generic Ultra-High Performance Concrete Mixed in the Field

---

Abstract

Most field applications of UHPC in the UShave utilized proprietary materials. This study describes one of the earliest field applications of a generic blend of UHPC in the US. Material properties of the field-mixed material are described and compared to their lab-mixed counterparts. The durability resistance of the field mix and the family of mixes from which it originated is investigated by evaluating the presence and distribution of air voids, the ingress of chlorides, and the material's resistance to freeze-thaw cycling. It is shown that the mix, like its commercial counterpart, has extremely high resistance to freeze-thaw cycling and chloride penetration.
