Concrete is a composite material consist of aggregate (gravel and sand), cement and water. This material reigns supreme in the construction industry, captivating builders with its exceptional compressive strength, unwavering durability, and boundless versatility. Plain concrete has a very low tensile strength, limited ductility and little resistance to cracking. To enhance mechanical properties of concrete (compressive strength, tensile strength usually added fibers to it. Researchers are cheering the addition of fibers to various materials. This research discusses the effects of E- glass fibers on the mechanical properties and workability of concrete. Experimental programmer consists of conducting compressive strength test, flexural strength test and split tensile strength and workability of concrete containing varying proportions of E-glass fiber. In our research we used the E-Glass fibers at different percentages as 0%.0.2%,0.4%.0.6% by the volume of fracture on C30 grade of mix proportion (1: 3: 1.8) with water cement ratio 0.56. From the results of experiments turns out that the Adding 0.2% glass fibers to concrete significantly improves its flexural strength (11.7%) and slightly boosts compressive (4.4%) and splitting tensile (6.16%) strength at 28 days. GFRC specimens also exhibit more resilient behavior under testing compared to plain concrete. However, workability declines with increasing fiber content
