The main objective of this research paper was to investigate the performances of M25 grade of concrete mix using hybrid fiber reinforced concrete such as basalt fiber reinforced concrete (BFRC) & polypropylene fiber (PP) on the normal mix & hybrid fiber mix having trial mix proportions 1:1.85:3.45with water cement ratio is 0.42 to study the behavior of hybrid fiber on the compressive strength, flexural strength, spilt tensile strength. the result obtained from test has been compared & analyzed with normal concrete mix prepared with (0.0% fibers). The relationship is established between compressive strength , workability, flexural strength, split tensile strength can be represented by graphically & mathematically. Research data was clearly shows that variation in fiber percentages shows decreases the compressive strength & split tensile strength of concrete.

Keywords: basalt fibers, polypropylene fibers, spilt tensile strength, compaction factor, workability, concrete mix, hybrid fiber.
