Abstract - The abstract describes the investigation of the behavior of glass fiber and fly ash in concrete. Concrete is a material that is weak in tension and prone to cracking and scaling. To enhance its performance, various additives, both chemical and mineral, have been used, including fly ash and glass fiber. Glass fiber, an inorganic fiber derived from molten glass, offers high tensile strength and fire resistance, which can reduce damage during fire accidents. Adding these fibers to concrete significantly improves its compressive strength, tensile strength, and split tensile strength. The study aims to test glass fiber concrete and assess the impact of fibers on concrete strength.Fly ash, a waste product from thermal power plants, presents environmental concerns. However, using fly ash in concrete offers environmental benefits, such as reducing cement requirements and saving raw materials like limestone. The investigation explores the utilization of fly ash in cement concrete as a partial replacement of cement and as an additive, providing an eco-friendly approach for its disposal and reuse.The abstract also mentions the effects of fibers in concrete, which include controlling cracking, reducing permeability, and minimizing water bleeding. Fly ash is described as a supplementary cementitious material used alongside Portland cement to enhance the properties of hardened concrete through hydraulic or pozzolanic activity.
