Ultra-high-performance concrete (UHPC) has gained worldwide popularity due to its high mechanical performance. This research studied the influence of adding a mixture of two fibers (steel and PVA) on the compressive strength, modulus of elasticity, and flexural tensile strength of UHPC. The mixtures were prepared by adding steel fibers and PVA fibers using a standard procedure defined in the research, which is the time to mix the dry materials and the time to mix the admixture and water.

- Strain-Hardening Cement-Based Composites (SHCCs) provide high toughness and durability but are not widely used due to challenges in developing effective analytical models for their optimization and design.
- The mechanical response of SHCCs is influenced by multiple factors, including fiber characteristics and matrix strength, making it complex to predict.
- This research reviews the mechanisms behind SHCC cracking and offers predictive techniques for its tensile behavior, highlighting research gaps for further investigation to enhance the use of SHCC in resilient structures.
