“…Liu et al, 2014) claimed that adding steel fibres to UHPC does not increase its compressive strength and ductility, even if the volume content is greater than 2%. Numerous investigations (Harish et al, 2013;Hassan et al, 2012) have discovered that the measured descending portion of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) cylinders under compression has a wide dispersion due to a variety of parameters such as fibre orientation, distribution, fibre alignment in formwork, concreting operations, and measuring technique.…”

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.

“…In most cases, four-point bending test are suggested to predict the flexural properties of the materials. The four-point flexure test is used to evaluate the stress strain characteristics of UHPC mortar, in which the high stress peak, strain peak noticed [5]. The finite element computations of the stress and strain distribution on the tensile surface of a four-point bend specimen of a 13Cr stainless steel (SS) are carried out to validate the experimental result [6].…”

Concrete can be considered as the ultimate construction material since it is the most widely used in the construction materials due to its extensive strength and reasonable cost. Recent years, large investments have been spent for studies on the new advanced materials to enhance the performance and functionality of conventional concrete especially for bridge structure. The application of Ultra-high-performance concrete (UHPC) as advanced materials in bridge application is well established since it able to construct 100m long highway bridge without reinforcement, while fiber reinforced polymers (FRP) required some studies on the optimum composition for bridge application. In this paper, A33 composite FRP from the previous research is studied under 4-point bending test to study the flexural behavior and compared to the UHPC. Three-dimensional finite element analysis of FRP and UHPC I-beam are modelled using Abaqus software to determine and compare the beam deflection and stress. The deflection and stress UHPC and FRP I-beam model being validated with experimental result of four-point bending test and theoretical of equivalent method in previous research. The results from the analytical and experimental are compared and shows good agreements. The presented modeling offers an economical and efficient tool to investigate the structural performance of FRP and UHPC in construction materials.
