Abstract: This study focuses on the experimental investigation of Partial Replacement of Steel Rebar with Micro Bar Reinforcement in Concrete, combined with the use of 10% Micro Silica as a partial replacement for cement. The main objective of this research is to enhance the strength, ductility, and durability of concrete while reducing the dependency on conventional steel reinforcement, which is often prone to corrosion and increases the overall cost of maintenance in reinforced concrete structures. With the rapid expansion of infrastructure development, the demand for advanced and sustainable construction materials has significantly increased. Therefore, this study aims to explore the potential of micro rebar and micro silica as innovative materials that contribute to both mechanical performance and sustainability in construction. In this experimental program, concrete cubes were prepared with a 10% replacement of cement by micro silica (by weight) and an addition of 10 kg of micro rebar per cube. Micro silica, a by-product of the silicon and ferrosilicon alloy industries, is a highly reactive pozzolanic material that enhances the microstructure of concrete by filling voids and refining pores. This results in improved compressive strength, reduced permeability, and greater durability. On the other hand, micro rebar, which consists of fine steel fibers or micro steel rods, serves as an alternative reinforcement material that provides better tensile strength, impact resistance, and crack control. It effectively bridges micro-cracks and prevents their propagation, thereby enhancing the toughness and post-cracking behavior of the concrete. Tests such as compressive strength, split tensile strength, and flexural strength were conducted after standard curing periods to compare the modified concrete with conventional reinforced concrete. The addition of micro silica improved the bonding between the cement paste and aggregates, while micro rebar enhanced the load-carrying capacity and ductility. The combined effect of these materials resulted in concrete that exhibits improved performance under both compressive and tensile loads. The results from this study are expected to show that the integration of micro silica and micro rebar reinforcement not only improves the mechanical and durability properties of concrete but also promotes a sustainable and cost-effective approach to construction. This research encourages the use of alternative and innovative materials to overcome the limitations of traditional reinforcement systems. In conclusion, the project demonstrates that the use of micro bar reinforcement and micro silica can serve as a reliable and eco-friendly solution for the future of concrete technology, contributing to long-lasting, corrosion-resistant, and high- performance concrete structures.
