The use of fiber reinforcement enhances the material's toughness, impact resistance, and fatigue resistance in concrete. Additionally, it improves the material's capacity to withstand cracking, water infiltration, and chloride intrusion, resulting in a substantial increase in the longevity of concrete buildings.
components of fine aggregates, cement as a binding agent, water and a number of additives. Concrete has been used for several decades because of its superior qualities hence creating the many uses of the material. However, there are some drawbacks to this material, for example, while concrete has some of the most outstanding features it does not do well when placed under tension stresses. As a result, improvements and subsequent research work have led to the development of fiber reinforced concrete (FRC). Fiber reinforced concrete (FRC) may be defined as the use of fibrous materials in the reinforcement of concrete.
Today, the importance of fiber reinforced concrete is increasing gradually. Thus, it has been established that the incorporation of fiber as reinforcement in concrete can improve some or all of the engineering properties of the concrete. This paper focuses on the comparison of fiber reinforced concrete (FRC) to the properties of reinforced cement concrete (RCC). The findings of this experimental investigation will give the comparison of normal concrete with fiber reinforced normal concrete. The following conclusions will have important implications toward improving the performance of concrete structures.
Key Words: RCC, FRC, compressive strength
1. INTRODUCTION Typically, fibers are employed in concrete to regulate the occurrence of plastic contraction cracking and drying shrinkage cracking. Additionally, they decrease the permeability of concrete, resulting in a reduction of water bleeding (Bertelsen et al., 2020). Fiber enhances the several forms of strength in concrete and aids in fracture reduction. Short fibers in FRC are uniformly dispersed in random orientations. Multiple types of fibers can be utilized in concrete for building purposes. Several types of fibers include steel fibers, glass fibers, synthetic fibers, natural fibers, and others. Each of the fibers contributes to different qualities of the concrete. Geometries, fiber materials, orientation, distribution, and densities are among the several elements that influence the strength of fiber-reinforced concrete.
1.1 Problem Statement The construction industry consistently explores novel materials and ways to improve structural performance, longevity, and sustainability. It is crucial to do a thorough comparison analysis of reinforced cement concrete (RCC) and fiber reinforced concrete (FRC) in order to assess their individual benefits, drawbacks, and appropriateness for different structural uses. 1.2 objective of this study The objective of this study is to comprehensively assess the mechanical, physical, and durability characteristics of both conventional concrete and fiber-reinforced concrete.
According to findings from recent research conducted on high-performance fiber-reinforced concrete, the incorporation of fibers resulted in the provision of residual strength and also reduced cracking. By incorporating steel fibers into the concrete mixture, a homogenous reinforcement is achieved (Gamage et al., 2024). This does not significantly enhance the mechanical qualities leading up to failure, but it does control the behavior after failure. Therefore, the brittle nature of ordinary concrete or RCC is transformed into the ductile behavior of steel fiberreinforced concrete. Once the matrix begins to break, the stresses are taken in by the bridging fibers, and the bending moments are redistributed. When the matrix of the concrete element is broken, it does not fail on its own. Instead, it

2. Literature Review According to Norouzi et al. (2021), building process efficiency remains central to boosting competitiveness and development of the construction industry. As a result, a lot of research has been promoted globally to solve the limitations and failings of the concrete materials and their uses in the improvement of building materials, methods, practices, and systems. Ferreira et al. (2021) found out that due to the environmental and natural aging, the structures go through a number of chemical and physical changes and as a
