Guidelines for UHPC Materials

Abstract

As UHPC exhibited ultra-high strength, good toughness, and superior durability that can be intended for use in precast/cast-in-situ structures, precast structure elements, and repairs for buildings and civil engineering structures and non-structural elements, the guidelines cover the following aspects: (1) Definitions of the terminology, classifications, requirements associated with fresh and hardened properties of UHPC, (2) Constituents and mixture design for UHPC, (3) Production controls and assessment of UHPC at different stages of manufacture. This guideline also proposes methods for bending test, uniaxial tensile test, and chloride migration test. We look forward to the ready integration of UHPC into the construction industry and hope UHPC will find a variety of applications. We also hope the guidelines are instrumental in the design and construction of this novel and versatile material. Finally, we would extend our sincere appreciation for those who involved in the preparation of the guidelines.
