ABSTRACT Rapid population growth and urbanization of a considerable increment are in demand for cement as construction material. It is vital to reduce the environmental effects associated with Ordinary Portland. Aggregate (coarse and fine) is mixed with cement and water to form concrete. A stone system is built since water is introduced to concrete. Although concrete is weak in tension and strong in compression, the reinforcement material is used to enhance its strength. Other reinforcing elements are used in concrete to assist it in withstanding stress. For several decades, fibers were added to concrete to improve and adjust its strength, typically attributed to Fiber Reinforced Concrete (FRC). Concrete's mechanical are strengthened through using fibres in studies. The study intends to examine the mechanical characteristics of hybrid concrete with M-25 strength to fibre reinforcement. Steel fibers and basalt fibers have been applied with varying (0.25 , 0.5 , 0.75 , and 1) % amounts of concrete. The results demonstrate that chopped basalt fibre behaves dramatically better during tensile stress, whereas crimped steel fibre gives better results over compression. The beams are indicated to break in shear, with most cracks occurring relatively close to the support. Correspondingly, the third middle part of the beam had some crack growth due to different fibre dosages. A hybrid fibre beam consisting of 0.75 steel and 0.25 is less expensive than a regular stirrup-equipped beam.
