Permeation and Fiber Matrix Bond Behaviour of Ultra High Performance Concrete – A Review

Abstract A brief review of the evolution and origins of Ultra-High Performance Concrete (UHPC) is covered in this article. UHPC is a unique concrete with unique features such as workability, mechanical properties, and durability that differs from regular concrete and high-performance concrete in terms of mix composition, needs, and manufacturing methods. In terms of the material ingredients of UHPC, Silica Fume (SF) plays a critical role in the production of UHPC due to its unique physical and chemical properties. Ground Granulated Blast Furnace Slag (GGBS), a highly reactive pozzolan similar to SF, is another viable contender among mineral admixtures. As a result, this article examines the effects of SF and GGBS in the UHPC combination. This paper also reviews the durability of UHPC in terms of water and chloride-ion permeability. A brief review of the importance of steel and polypropylene fibre (PPF) in UHPC blends, as well as their pull-out behaviour, is also reviewed.
