A Review in Technologies, Definitions, Properties and Applications of Ultra High-Performance Concrete (UHPC)

Abstract

Concrete technology has changed dramatically during the last decades, where the high-strength concrete concept has gone from 30 MPa to well over 100 MPa. In this paper, a review study has been conducted on ultra high-performance concrete (UHPC), however, researchers have a lot of definitions for this term, but all of them agreed that (UHPC) which refers to cement-based materials exhibiting superior properties, including compressive strength higher than 150 MPa with high ductility, and excellent durability. This paper reviews the theoretical principles of UHPC, definitions, raw materials, mixture design methods, successful mixture components with the required properties, challenges, and some of the successful applications of UHPC, focusing on bridge applications. The paper concluded by summarizing the benefits of using UHPC, the future of this superior concrete, current challenges and some recommendations for wider use.
