Structural Characteristics of GFRC Strength of GFRC is developed due to high contents of alkali resistant glass fibers and acrylic polymer. Since the cement contents are high, and the ratio of water to cement is low, the GFRC strength under compressive loads is high. These materials also possess great tensile and flexural strength. The fiber orientation determines the effectiveness of fiber resistance to loads. The fiber must be stiff to ensure the provision of required tensile strength. Thus, the performance of these materials is better than the normal concrete. The high fiber content bears the tensile loads, while the concrete is flexible due to the polymers. The physical properties of GFRC are better than the non-reinforced concrete. Steel reinforcement that has been suitably designed considerably increases the strength of products that are cast with normal concrete or GFRC. However, GFRC cannot substitute reinforced concrete if heavy loads are required to be endured. GFRC are best suitable for light loads. Applications of GFRC are vanity tops, wall panels, and other comparable products. The fiber orientation determines the effectiveness of fiber resistance to loads. The fiber must be stiff to ensure the provision of required tensile strength.
