Abstract - Glass Fiber-Reinforced Concrete (GFRC) is an
matrix provides the basic structure and strength for the material. The mix design of the matrix can be tailored to optimize the strength, workability, and other properties of the composite material [1]
advanced composite material incorporating alkali-resistant (AR) glass fibers into a cement matrix, significantly enhancing its mechanical properties, durability, and aesthetic capabilities. This review presents a detailed analysis of the composition, mechanical and durability properties, manufacturing techniques, applications and challenges of GFRC. The paper also identifies gaps in existing research and provides suggestions for future studies to further optimize the material’s performance. With its high corrosion resistance, improved strength characteristics, and versatility, GFRC holds great promise for a wide range of applications in construction, architecture, and infrastructure.
2.2. Glass Fibers Glass fibers are the main reinforcing element in GFRC. Alkali-resistant (AR) glass fibers are preferred as they offer resistance to the high alkalinity of the concrete matrix. The glass fibers are usually short strands or chopped fibers, although continuous filaments may also be used for specific applications. The fiber length, diameter, and surface treatment (e.g., sizing) affect the bond between the fibers and the matrix, as well as the mechanical properties of GFRC [2].

2.3. Additives
1. INTRODUCTION
Various additives and admixtures are used to enhance specific properties of GFRC. These may include plasticizers, accelerators, retarders, and air-entraining agents. These additives help control the setting time, improve workability, reduce segregation, and enhance the freeze-thaw resistance of GFRC [4].
Glass Fiber-Reinforced Concrete (GFRC) has garnered increasing interest due to its superior mechanical properties and durability compared to traditional concrete. GFRC is composed of a cementitious matrix reinforced with alkaliresistant (AR) glass fibers, which significantly enhance its tensile strength, flexural strength, crack resistance, and impact resistance. The material's lightweight nature, combined with its ability to be molded into intricate shapes, makes it highly suitable for both structural and nonstructural applications, particularly in architecture and construction.
3. PROPERTIES OF GLASS FIBER-REINFORCED CONCRETE GFRC exhibits superior properties compared to conventional concrete, especially in terms of mechanical strength, durability, and resistance to cracking and corrosion.
This paper presents a comprehensive review of the composition, mechanical properties, manufacturing methods, applications, challenges, and future directions of GFRC, with a particular focus on its impact on modern construction practices.
3.1. Mechanical Properties
Compressive Strength: GFRC typically has compressive strength similar to conventional concrete. The fibers do not significantly impact the compressive strength, but they improve other mechanical properties like tensile strength and fracture resistance [3].
Flexural Strength: One of the most notable advantages of GFRC is its increased flexural strength. The addition of glass fibers significantly enhances the material's ability to resist bending stresses, reducing crack propagation and increasing structural performance [1].
Tensile Strength: GFRC demonstrates improved tensile strength compared to ordinary concrete due
2. COMPOSITION OF GLASS FIBER-REINFORCED CONCRETE GFRC consists of three primary components: the cement matrix, glass fibers, and additives or admixtures. The relative proportions and characteristics of each component directly influence the material's properties. 2.1. Cement Matrix The cement matrix in GFRC typically consists of Portland cement, fine aggregates (sand), water, and admixtures. The
